DETAILED DESCRIPTION OF THE INVENTION

[0028] Hereinafter, examples of embodiments of a hub, an information processing device, and a program according to the technology of the present disclosure will be described with reference to the accompanying drawings.

[0029] First, the terms used in the following description will be explained.

[0030] CPU is an abbreviation for "Central Processing Unit". GPU is an abbreviation for "Graphics Processing Unit". NVM is an abbreviation for "Non-volatile memory". RAM is an abbreviation for "Random Access Memory". DRAM is an abbreviation for "Dynamic Random Access Memory". SRAM is an abbreviation for "Static Random Access Memory". HDD is an abbreviation for "Hard Disk Drive". SSD is an abbreviation for "Solid State Drive". ASIC is an abbreviation for "Application Specific Integrated Circuit". PLD is an abbreviation for "Programmable Logic Device". FPGA is an abbreviation for "Field-Programmable Gate Array". SoC is an abbreviation for "System-on-a-Chip". IC is an abbreviation for "Integrated Circuit". RFID is an abbreviation for "Radio Frequency Identifier". EL is an abbreviation for "Electro-Luminescence". WAN is an abbreviation for "Wide Area Network". LAN is an abbreviation for "Local Area Network". USB is an abbreviation for "Universal Serial Bus". I / F is an abbreviation for "Interface". ID is an abbreviation for "identifier".

[0031] [First embodiment] 1, the magnetic tape manufacturing process 10 is a process for manufacturing magnetic tape, and includes multiple processes such as a coating process (not shown), a cutting process 10A, a signal writing process 10B, and an assembly process 10C. In the coating process, a magnetic paint is applied to a base film, an orientation process is performed to align the orientation of the magnetic material in the applied magnetic paint, and then the magnetic paint is dried to form a roll R.

[0032] The cutting process 10A includes an unwinding section 12, a cutting section 14, and a winding section 16. The unwinding section 12 unwinds the roll R. The cutting section 14 cuts the roll R into tape shapes using a rotary knife 18 to match the tape width defined by the standard. This cutting process turns the roll R into multiple magnetic tape pieces MT each having a fixed tape width. The winding section 16 winds each magnetic tape piece MT cut by the cutting section 14 onto a hub 20A, thereby producing multiple pancake PCs. A pancake PC refers to a tape winding body in which the magnetic tape MT is wound around the hub 20A. In this technical field, such a tape winding body is generally referred to as a "pancake" and is used as raw material for intermediate processes or shipped as a finished product.

[0033] In the signal writing process 10B, the magnetic tape MT wound around the hub 20A is wound around the hub 20B. In the signal writing process 10B, the magnetic tape MT is unwound from the hub 20A and wound around the hub 20B, thereby transferring the magnetic tape MT from the hub 20A to the hub 20B. A servo writer 22 is disposed on the path along which the magnetic tape MT is transferred from the hub 20A to the hub 20B. In the signal writing process 10B, the servo writer 22 writes servo signals onto the magnetic tape MT while the magnetic tape MT is running. That is, the servo writer 22 writes servo signals onto the magnetic tape MT on the path along which the magnetic tape MT is transferred from the hub 20A to the hub 20B. The magnetic tape MT with the written servo signals is wound around the hub 20B, thereby forming a pancake PC. The servo signals refer to magnetic signals used to confirm that a head that reads signals from the magnetic tape MT is tracking a predetermined position on the magnetic tape. In addition to writing the servo signals, the servo writer 22 also verifies the written servo signals.

[0034] In the assembling process 10C, the magnetic tape MT, on which the servo signals were written in the signal writing process 10B, is pulled out from the pancake PC and wound around the hub 20C inside the cartridge CR, thereby assembling the magnetic tape MT into the cartridge CR. This completes the cartridge CR. The magnetic tape MT unwound from one pancake PC is divided and assembled into multiple cartridges CR. For example, 5 to 20 cartridges CR are manufactured from one pancake PC.

[0035] For ease of explanation, hereinafter, when there is no need to distinguish between the hubs 20A, 20B, and 20C, they will be referred to as "hub 20."

[0036] However, the hub 20 may become deformed, worn, or soiled due to the pressure of the magnetic tape MT being wound around it and the influence of the external environment (temperature, humidity, etc.). This may cause instability in the winding and pulling out of the magnetic tape MT, damage the magnetic tape MT, or soil the magnetic tape MT. To prevent such situations from occurring, it is necessary to determine as accurately as possible whether the hub 20 is usable. To achieve this, it is necessary to manage as accurately as possible the dimensions of the hub 20, the quality of the hub 20, the number of times the hub 20 has been used, the expiration date of the hub 20, the usage history of the hub 20, and the type of hub 20.

[0037] Therefore, in the first embodiment, a hub management system 30 is used as an example, as shown in Fig. 2. The hub management system 30 includes a management device 32, a reader / writer , and an RFID tag .

[0038] The management device 32 includes a management device main body 38 , a reception device 40 , and a display 42 , and is used by an administrator 43 .

[0039] A reception device 40 is connected to the management device main body 38. The reception device 40 has a keyboard 44, a mouse 46, etc., and receives instructions from an administrator 43. In the example shown in FIG. 2, the keyboard 44 and the mouse 46 are shown as the reception device 40, but this is merely an example, and a touch panel and / or a tablet, etc. may be used instead of the keyboard 44 and / or the mouse 46, or together with the keyboard 44 and / or the mouse 46. At least one of the keyboard 44, the mouse 46, a touch panel or tablet that accepts proximity input, a voice input device that accepts voice input, an imaging device that accepts gesture input, and a sensor may be used as the reception device 40. The connection between the reception device 40 and the management device main body 38 may be wired or wireless.

[0040] A display 42 is connected to the management device main body 38. Examples of the display 42 include an EL display and a liquid crystal display. The display 42 displays various information (for example, images and text) under the control of the management device main body 38.

[0041] The hub 20 of the pancake PC includes a hub body 48. A magnetic tape MT for the pancake PC is wound around the hub body 48. The hub body 48 is formed in a cylindrical shape, and the magnetic tape MT is wound around an outer peripheral surface 48A of the hub body 48.

[0042] A wireless data carrier is provided in the hub body 48. The wireless data carrier may be embedded in the hub body 48 by processing the hub body 48 after molding, or by embedding the wireless data carrier during molding (e.g., molding) of the hub body 48. It is preferable that the entire wireless data carrier be embedded in the hub body 48, but the technology of the present disclosure also applies when only a portion of the wireless data carrier is embedded in the hub body 48, and the technology of the present disclosure also applies when the wireless data carrier is attached to the inner or outer circumferential surface of the hub body 48.

[0043] The wireless data carrier may be in the form of a stick, label, card, or coin. The wireless data carrier is an electromagnetic induction carrier. Note that the electromagnetic induction carrier is merely an example, and any carrier that can transmit and receive information in a contactless manner, such as an electromagnetic coupling carrier, a microwave carrier, or an optical carrier, may be used.

[0044] 2, an RFID tag 36 is shown as an example of a wireless data carrier embedded in the hub body 48. The RFID tag 36 is an example of a "contactless storage medium" according to the technology of the present disclosure. Information about the magnetic tape MT, information about the hub body 48, and the like is written to the RFID tag 36.

[0045] The reader / writer 34 is communicably connected to the management device main body 38, and various types of information are exchanged between the reader / writer 34 and the management device main body 38. The reader / writer 34 is used by a worker 50. The reader / writer 34 is provided with a reception device 52. The reception device 52 is a device that receives instructions from the worker 50. An example of the reception device 52 is a button (for example, a push button). The button is operated by the worker 50. When the reception device 52 receives an instruction, the reader / writer 34 communicates with the management device main body 38 and writes information to the RFID tag 36 in a contactless manner, or reads information from the RFID tag 36 in a contactless manner.

[0046] 3 , the management device main body 38 includes a computer 56, a communication I / F 58, and a bus 60. The computer 56 is an example of a “computer” according to the technology of the present disclosure, and includes a processor 62, a storage 64, and a RAM 66. The processor 62, the storage 64, and the RAM 66 are connected to the bus 60. The communication I / F 58 is also connected to the bus 60.

[0047] The processor 62 is an example of a "processor" according to the technology of the present disclosure. The processor 62 is, for example, a CPU, and controls the entire management device 32. Here, a CPU is given as an example of the processor 62, but this is merely an example, and the processor 62 may also have a CPU and a GPU. The GPU operates under the control of the CPU and is responsible for executing image-related processing. Furthermore, the processor 62 may be one or more CPUs that integrate GPU functionality, or one or more CPUs that do not integrate GPU functionality.

[0048] A memory is connected to the processor 62. The memory is an example of the "memory" according to the technology of the present disclosure and includes a storage 64 and a RAM 66. The storage 64 is a non-volatile storage device that stores various programs, various parameters, and the like. Examples of the storage 64 include a flash memory and a HDD. Note that the flash memory and the HDD are merely examples, and at least one of a flash memory, a HDD, a magnetoresistive memory, and a ferroelectric memory may be used as the storage 64.

[0049] The RAM 66 is a memory that temporarily stores information and is used as a work memory by the processor 62. The RAM 66 may be, for example, a DRAM or an SRAM.

[0050] The communication I / F 58 is connected to a network (not shown). The network may be configured, for example, as at least one of a LAN, a WAN, etc. An external communication device (not shown) and the like are connected to the network, and the communication I / F 58 controls the exchange of information with the external communication device via the network. In the example shown in FIG. 3, the reader / writer 34 is shown as an example of the external communication device. For example, the communication I / F 58 transmits information to the reader / writer 34 in response to a request from the processor 62. The communication I / F 58 also receives information transmitted from the reader / writer 34 and outputs the received information to the processor 62 via the bus 60.

[0051] In the management device 32, the reception device 40 is connected to the bus 60. An instruction received by the reception device 40 is acquired by the processor 62.

[0052] In the management device 32, the display 42 is connected to the bus 60. Under the control of the processor 62, the display 42 displays various information (for example, images, text, etc.).

[0053] In addition to the accepting device 52, the reader / writer 34 includes a computer 68, a first communication I / F 70, a second communication I / F 72, and a bus 74. The computer 68 includes a processor 76, an NVM 78, and a RAM 80. The accepting device 52, the first communication I / F 70, the second communication I / F 72, the processor 76, the NVM 78, and the RAM 80 are connected to the bus 74.

[0054] The processor 76 is, for example, a CPU, and controls the entire reader / writer 34. A memory is connected to the processor 76. The memory includes an NVM 78 and a RAM 80. An example of the NVM 78 is a flash memory. The flash memory is merely an example, and at least one of a flash memory, a magnetoresistive memory, and a ferroelectric memory may be used as the NVM 78.

[0055] The RAM 80 is a memory that temporarily stores information and is used as a work memory by the processor 76. The RAM 80 may be, for example, a DRAM or an SRAM.

[0056] The first communication I / F 70 is connected to the RFID tag 36 so as to be able to communicate wirelessly. The first communication I / F 70 controls the exchange of information between the processor 76 and the RFID tag 36. The processor 76 writes information to the RFID tag 36 and reads information from the RFID tag 36 by transmitting and receiving information to and from the RFID tag 36 via the first communication I / F 70. When the processor 76 writes information to the RFID tag 36, the first communication I / F 70 transmits information to the RFID tag 36 in response to a request from the processor 76. When the processor 76 reads information from the RFID tag 36, the first communication I / F 70 receives the information transmitted from the RFID tag 36 and outputs the received information to the processor 76 via the bus 74.

[0057] The second communication I / F 72 is connected to the same network as the communication I / F 58 of the management device 32. The second communication I / F 72 is responsible for sending and receiving information to and from the management device 32 via the network. For example, the second communication I / F 72 receives information sent from the management device 32 and outputs the received information to the processor 76 via the bus 74. The second communication I / F 72 also sends information to the management device 32 in response to a request from the processor 76.

[0058] The RFID tag 36 includes a computer 82, a communication I / F 84, and a bus 86. The computer 82 includes a processor 88, an NVM 90, and a RAM 92. The communication I / F 84, the processor 88, the NVM 90, and the RAM 92 are connected to the bus 86.

[0059] The processor 88 is, for example, a CPU, and controls the entire RFID tag 36. A memory is connected to the processor 88. The memory includes an NVM 90 and a RAM 92. An example of the NVM 90 is a ferroelectric memory. The ferroelectric memory is merely an example, and any nonvolatile memory such as a magnetoresistive memory may be used.

[0060] The RAM 92 is a memory that temporarily stores information and is used as a work memory by the processor 88. The RAM 92 may be, for example, a DRAM or an SRAM.

[0061] The communication I / F 84 is connected to the reader / writer 34 so as to be able to communicate wirelessly. The communication I / F 84 controls the exchange of information between the processor 88 and the reader / writer 34. That is, the processor 88 transmits and receives information to and from the reader / writer 34 via the communication I / F 84.

[0062] The communication I / F 84 transmits information in response to a request from the processor 88 to the reader / writer 34. The communication I / F 84 also receives information transmitted from the reader / writer 34 and outputs the received information to the processor 88 via the bus 86.

[0063] In the RFID tag 36, the communication I / F 84 receives a request from the reader / writer 34, and the processor 88 writes information to the NVM 90 and reads information from the NVM 90 in response to the request received by the communication I / F 84.

[0064] As an example, as shown in FIG. 4, in the RFID tag 36, hub-related information 94 is stored in the NVM 90. The hub-related information 94 includes a hub ID 96 and hub change characteristic information 98. The hub ID 96 is an example of "hub-specific information" according to the technology of the present disclosure. The hub ID 96 is information that can identify the hub body 48 to which the RFID tag 36 is attached, and is assigned to each of the multiple hub bodies 48 as mutually different information (i.e., information that can individually identify the hub body 48).

[0065] The final content of the hub-related information 94 is determined, for example, by the administrator 43. The final content of the hub-related information 94 is accepted by the accepting device 40 and written to the RFID tag 36 by the reader / writer 34 (i.e., stored in the NVM 90).

[0066] The hub-related information 94 stored in the RFID tag 36 is read from the RFID tag 36 by the reader / writer 34. The hub-related information 94 read from the RFID tag 36 by the reader / writer 34 is acquired by the management device 32.

[0067] The hub change characteristic information 98 is associated with the hub ID 96. The hub change characteristic information 98 is information that indicates the change characteristic of the hub main body 48. Examples of the change characteristic of the hub main body 48 include the dimensions of a deformable portion included in the hub main body 48, the quality of the hub main body 48, and the change characteristic of the usage history of the hub main body 48.

[0068] The hub change characteristic information 98 includes dimension information 100, quality information 102, usage history information 104, and hub usability information 106.

[0069] The dimension information 100 is information indicating the dimensions of the deformable portions of the hub body 48 (for example, the outer diameter and inner diameter of one end, the thickness of the one end, the outer diameter and inner diameter of the other end, the thickness of the other end, the outer diameter and inner diameter of the central portion, the thickness of the central portion, and the overall length in the axial direction of the hub body 48). The dimensions of the deformable portions of the hub body 48 are measured by, for example, the manager 43 or the worker 50.

[0070] The quality information 102 is information indicating the quality of the hub body 48. The quality of the hub body 48 is evaluated by, for example, the administrator 43. The quality of the hub body 48 is expressed, for example, as excellent (◎), good (◯), fair (△), and poor (×). The quality of the hub body 48 can also be expressed as the expiration date of the hub body 48 (for example, 20xx year x month x day, etc.). In the example shown in FIG. 4, the quality information 102 includes expiration date information 102A. The expiration date information 102A is information indicating the expiration date of the hub body 48.

[0071] The usage history information 104 is information that indicates the usage history of the hub body 48. The usage history refers to the history of how the hub body 48 has been used, such as the location where the hub body 48 was used, the period during which the hub body 48 was used, and the person who used the hub body 48. The usage history may be managed by the manager 43 or the worker 50, or may be managed by various sensors installed in each process included in the magnetic tape manufacturing process 10 (for example, the cutting process 10A, the signal writing process 10B, and the assembling process 10C).

[0072] The hub usability information 106 is information indicating whether or not the hub main body 48 can be used. Whether or not the hub main body 48 can be used (hereinafter also referred to as "hub usability") is determined by the administrator 43, for example.

[0073] As an example, as shown in FIG. 5 , in the management device 32, management processing is performed by the processor 62. A management processing program 108 is stored in the storage 64. The management processing program 108 is an example of a "program" according to the technology of the present disclosure. The processor 62 reads the management processing program 108 from the storage 64 and executes the read management processing program 108 on the RAM 66 to perform management processing. The management processing is realized by the processor 62 operating as a display control unit 62A and a change unit 62B in accordance with the management processing program 108.

[0074] As an example, as shown in FIG. 6 , the management device 32 acquires hub-related information 94 from the RFID tag 36 via the reader / writer 34. Specifically, the reader / writer 34 reads the hub-related information 94 from the RFID tag 36. The reader / writer 34 transmits the hub-related information 94 to the management device 32. In the management device 32, the communication I / F 58 receives the hub-related information 94 transmitted from the reader / writer 34. For example, the processor 62 (see FIGS. 3 and 5 ) stores the hub-related information 94 received by the communication I / F 58 in the storage 64 (see FIGS. 3 and 5 ). For example, the processor 62 processes the hub-related information 94 stored in the storage 64 in accordance with an instruction received by the receiving device 40. An example of processing by the processor 62 is changing the hub-related information 94.

[0075] The display control unit 62A causes the display 42 to display a list of the hub ID 96, the dimensions indicated by the dimension information 100, the quality indicated by the quality information 102, the usage history indicated by the usage history information 104, and the usability of the hub indicated by the hub usability information 106. Specifically, the display control unit 62A generates a hub management screen 110 based on the hub-related information 94 received by the communication I / F 58. Then, the display control unit 62A causes the display 42 to display the generated hub management screen 110. The hub management screen 110 includes the hub ID 96, the dimensions indicated by the dimension information 100, the quality indicated by the quality information 102, the usage history indicated by the usage history information 104, and the usability of the hub indicated by the hub usability information 106.

[0076] Display 42 is an example of a "first presentation device" according to the technology of the present disclosure. Hub usability information 106 is an example of "first information" according to the technology of the present disclosure. Whether or not the hub can be used, as indicated by hub usability information 106, is an example of "contents of first information" according to the technology of the present disclosure.

[0077] 6 shows an example in which the display control unit 62A outputs information for displaying the contents of the hub-related information 94 on the display 42 (in the example shown in FIG. 6, the hub management screen 110), but the technology of the present disclosure is not limited to this. For example, the processor 62 of the management device 32 may output information for displaying the contents of the hub-related information 94 to various presentation devices. In this case, for example, instead of displaying the contents on the display 42, or in addition to displaying the contents on the display 42, the contents of the hub-related information 94 (e.g., the hub ID 96 and the contents of the hub change characteristic information 98 associated with the hub ID 96) may be output as audio by an audio playback device or recorded on a recording medium (e.g., paper) by a printer.

[0078] 7, the receiving device 40 receives an instruction (hereinafter also referred to as a "change instruction") from the administrator 43 to change the content of the hub change characteristic information 98. The change instruction includes specific changes to be made to the hub change characteristic information 98. When the change instruction is received by the receiving device 40, the change unit 62B generates a change instruction signal 112 in accordance with the change instruction and transmits the generated change instruction signal 112 to the reader / writer 34 via the communication I / F 58. The change instruction signal 112 includes a signal indicating the specific content of the hub change characteristic information 98 after the change.

[0079] The reader / writer 34 receives the change instruction signal 112 transmitted from the management device 32 and transmits the received change instruction signal 112 to the RFID tag 36. In the RFID tag 36, the change instruction signal 112 transmitted from the reader / writer 34 is received by the communication I / F 84. The processor 88 changes the content of the hub change characteristic information 98 in accordance with the change instruction signal 112 received by the communication I / F 84. A change to the content of the hub change characteristic information 98 refers to, for example, at least one of a change to the content of the dimension information 100, a change to the content of the quality information 102, a change to the content of the usage history information 104, and a change to the content of the hub usability information 106. In this manner, the hub change characteristic information 98 is changed by the change unit 62B in accordance with an external instruction (here, as an example, a change instruction received by the reception device 40). Note that the processing performed by the display control unit 62A and the processing performed by the change unit 62B are examples of “processing using hub change characteristic information” according to the technology disclosed herein.

[0080] Next, the operation of the hub management system 30 according to the first embodiment will be described with reference to FIG.

[0081] 8 shows an example of the flow of management processing performed by the processor 62 of the management device 32 according to the first embodiment. Note that the description here is based on the assumption that the hub-related information 94 is stored in the RFID tag 36.

[0082] 8, first, in step ST10, the display control unit 62A determines whether or not the hub-related information 94 has been received by the communication I / F 58. If the hub-related information 94 has not been received by the communication I / F 58 in step ST10, the determination is negative, and the management process proceeds to step ST16. If the hub-related information 94 has been received by the communication I / F 58 in step ST10, the determination is positive, and the management process proceeds to step ST12.

[0083] In step ST12, the display control unit 62A generates the hub management screen 110 (see FIG. 6) based on the hub-related information 94 received in step ST10 by the communication I / F 58. After the processing of step ST12 is executed, the management processing proceeds to step ST14.

[0084] In step ST14, the display control section 62A causes the display 42 to display the hub management screen 110 generated in step ST12 (see FIG. 6). After the processing of step ST14 is executed, the management processing proceeds to step ST16.

[0085] In step ST16, the change unit 62B determines whether or not a change instruction from the administrator 43 has been accepted by the acceptance device 40. If the change instruction from the administrator 43 has not been accepted by the acceptance device 40 in step ST16, the determination is negative, and the management process proceeds to step ST22. If the change instruction from the administrator 43 has been accepted by the acceptance device 40 in step ST16, the determination is positive, and the management process proceeds to step ST18.

[0086] In step ST18, the change unit 62B generates a change instruction signal 112 (see FIG. 7) in accordance with the change instruction accepted by the accepting device 40 in step ST16. After the process of step ST18 is executed, the management process proceeds to step ST20.

[0087] In step ST20, the change unit 62B transmits the change instruction signal 112 generated in step ST18 to the RFID tag 36 via the reader / writer 34 (see FIG. 7). As a result, in the RFID tag 36, the change instruction signal 112 transmitted from the reader / writer 34 is received by the communication I / F 84. The processor 88 changes the content of the hub change characteristic information 98 in accordance with the change instruction signal 112 received by the communication I / F 84 (see FIG. 7). After the processing of step ST20 is executed, the management processing proceeds to step ST22.

[0088] In step ST22, the processor 62 determines whether or not a condition for terminating the management process (hereinafter referred to as the "termination condition") has been satisfied. One example of the termination condition is that an instruction to terminate the management process has been accepted by the acceptance device 40. If the termination condition has not been satisfied in step ST22, the determination is negative, and the management process proceeds to step ST10. If the termination condition has been satisfied in step ST22, the determination is positive, and the management process terminates.

[0089] As described above, in the hub management system 30, the RFID tag 36 is provided to the hub main body 48 (see FIG. 2). The RFID tag 36 stores hub-related information 94. The hub-related information 94 includes a hub ID 96 and hub change characteristic information 98. The hub change characteristic information 98 is associated with the hub ID 96. The hub main body 48 is identified from the hub ID 96, and the change characteristic of the hub main body 48 is identified from the hub change characteristic information 98. This can contribute to handling of the hub 20 according to the change characteristic of the hub main body 48 (for example, handling of the hub 20 based on a determination of which hub 20 should be used for which device in which process, which hub main body 48 is usable, and / or which hub main body 48 is unusable, etc.).

[0090] Furthermore, in the hub management system 30, the RFID tag 36 stores hub change characteristic information 98, which includes dimensional information 100 (see FIG. 4). The dimensional information 100 is the dimensions of the deformable portions of the hub body 48. This can contribute to the handling of the hub 20 according to the dimensions of the deformable portions of the hub body 48.

[0091] Furthermore, in the hub management system 30, the RFID tag 36 stores hub change characteristic information 98, which includes quality information 102 (see FIG. 4). The quality information 102 is information that indicates the quality of the hub body 48. This can contribute to the handling of the hub 20 according to the quality of the hub body 48.

[0092] Furthermore, in the hub management system 30, the quality information 102 includes expiration date information 102A (see FIG. 4). The expiration date information 102A is information that indicates the expiration date of the hub body 48. This can contribute to the handling of the hub 20 in accordance with the expiration date of the hub body 48.

[0093] Furthermore, in the hub management system 30, the RFID tag 36 includes usage history information 104 (see FIG. 4). The usage history information 104 is information that indicates the usage history of the hub main body 48. This can contribute to the handling of the hub 20 depending on whether the hub main body 48 is usable or not.

[0094] Furthermore, in the hub management system 30, the RFID tag 36 includes hub usability information 106 (see FIG. 4). The hub usability information 106 is information indicating whether the hub main body 48 can be used. This can contribute to the handling of the hub 20 depending on whether the hub main body 48 can be used.

[0095] Furthermore, in the hub management system 30, the hub change characteristic information 98 stored in the RFID tag 36 is changed in accordance with an instruction ("change instruction" in the example shown in FIG. 7) given by the administrator 43. Therefore, the hub change characteristic information 98 can be changed at a timing intended by the administrator 43.

[0096] Furthermore, in the hub management system 30, the RFID tag 36 is embedded in the hub body 48. Therefore, compared to when the entire RFID tag 36 is exposed from the hub body 48, the portion of the RFID tag 36 that is embedded in the hub body 48 can be protected from external stimuli (for example, impacts, dust, etc.).

[0097] Furthermore, in the hub management system 30, an RFID tag 36 is provided on a hub main body 48 around which a magnetic tape MT for a pancake PC is wound (see FIG. 2). The RFID tag 36 stores hub-related information 94. The hub-related information 94 includes a hub ID 96 and hub change characteristic information 98. The hub change characteristic information 98 is associated with the hub ID 96. The hub main body 48 is identified from the hub ID 96, and the change characteristic of the hub main body 48 is identified from the hub change characteristic information 98. This can contribute to handling of the hub 20 according to the change characteristic of the hub main body 48 around which the magnetic tape MT for a pancake PC is wound.

[0098] Furthermore, in the hub management system 30, the hub usability indicated by the hub usability information 106 is displayed on the display 42 (see FIG. 6). Therefore, the administrator 43 can know whether the hub main body 48 is usable or not.

[0099] In the first embodiment described above, a handheld reader / writer 34 (see FIG. 2) is exemplified, but the technology of the present disclosure is not limited to this, and a stationary reader / writer may be used instead of the handheld reader / writer 34 or together with the handheld reader / writer 34. The stationary reader / writer may be installed, for example, within a range where wireless communication is possible from the location where the hub 20 is installed.

[0100] [Second embodiment] In the first embodiment, an example was given in which the administrator 43 determines whether the hub main body 48 can be used by referring to the hub usability information included on the hub management screen 110. However, in the second embodiment, an example will be described in which the administrator 43 determines whether the hub main body 48 can be used without relying on the hub usability information 106. Note that in the second embodiment, the same components as in the first embodiment are denoted by the same reference numerals and their description will be omitted, and mainly the parts that differ from the first embodiment will be described.

[0101] 9, hub-related information 114 according to the second embodiment differs from hub-related information 94 according to the first embodiment in that it further includes facility information 115 and type information 116. The facility information 115 is associated with a hub ID 96. The type information 116 is also associated with the hub ID 96.

[0102] The equipment information 115 is information that can identify equipment that can be used with the hub body 48. Equipment that can be used with the hub body 48 refers to, for example, equipment that has been determined by the administrator 43 or the like to be usable with the hub body 48 (for example, various types of equipment used in the magnetic tape manufacturing process 10). The type information 116 is information that indicates the type of magnetic tape MT that can be used with the hub body 48. The type of magnetic tape MT that can be used with the hub body 48 refers to, for example, the type of magnetic tape MT that has been determined by the administrator 43 or the like to be usable with the hub body 48.

[0103] 10, a management processing program 118 is stored in the storage 64. The management processing program 118 is an example of a "program" according to the technology of the present disclosure. The processor 62 performs management processing by reading the management processing program 118 from the storage 64 and executing the read management processing program 118 on the RAM 66. The management processing according to the second embodiment is realized by the processor 62 operating as a display control unit 62A, a change unit 62B, and a determination unit 62C in accordance with the management processing program 118.

[0104] As an example, as shown in FIG. 11 , the management device 32 acquires hub-related information 114 from the RFID tag 36 via the reader / writer 34. Specifically, the reader / writer 34 reads the hub-related information 114 from the RFID tag 36. The reader / writer 34 transmits the hub-related information 114 to the management device 32. In the management device 32, the communication I / F 58 receives the hub-related information 114 transmitted from the reader / writer 34. For example, the processor 62 (see FIGS. 3 and 5 ) stores the hub-related information 114 received by the communication I / F 58 in the storage 64 (see FIGS. 3 and 5 ). For example, the processor 62 processes the hub-related information 114 stored in the storage 64 in accordance with an instruction received by the receiving device 40. An example of processing by the processor 62 is changing the hub-related information 114.

[0105] In the management device 32, the determination unit 62C acquires information other than the hub usability information 106 (i.e., the dimension information 100, the quality information 102, and the usage history information 104) from the hub change characteristic information 98 included in the hub-related information 114 received by the communication I / F 58. The determination unit 62C also acquires the equipment information 115 and the type information 116 from the hub-related information 114 received by the communication I / F 58.

[0106] The determination unit 62C then determines whether the hub body 48 is usable based on the dimension information 100, the quality information 102, the usage history information 104, the equipment information 115, and the type information 116. For example, if at least one of the dimensions indicated by the dimension information 100, the quality indicated by the quality information 102, the usage history indicated by the usage history information 104, the equipment indicated by the equipment information 115, and the type indicated by the type information 116 fails, the determination unit 62C determines that the hub body 48 identified from the hub ID 96 is unusable, regardless of the content of the hub usability information 106. Conversely, if all of the dimensions indicated by the dimension information 100, the quality indicated by the quality information 102, the usage history indicated by the usage history information 104, the equipment indicated by the equipment information 115, and the type indicated by the type information 116 pass, the determination unit 62C determines that the hub body 48 identified from the hub ID 96 is usable, regardless of the content of the hub usability information 106.

[0107] The criteria for determining whether a product is pass or fail (for example, acceptable dimensions, acceptable quality, acceptable usage history, acceptable equipment, and acceptable type of magnetic tape MT) are stored, for example, as a table or an arithmetic formula in storage 64, and the determination unit 62C determines whether a product is pass or fail according to the table or the arithmetic formula.

[0108] In the second embodiment, the hub usability information 106 is an example of "first information" according to the technology of the present disclosure. The dimension information 100, the quality information 102, and the usage history information 104 are examples of "second information" according to the technology of the present disclosure.

[0109] The display control unit 62A generates a determination result screen 120 that displays the result determined by the determination unit 62C (hereinafter also referred to as the "determination result"). The display control unit 62A causes the display 42 to display the generated determination result screen 120. Note that the display 42 is an example of a "first presentation device," a "second presentation device," a "third presentation device," and a "fourth presentation device" according to the technology of the present disclosure.

[0110] If the determination unit 62C determines that the hub main body 48 is unusable, the determination result screen 120 displays the hub ID 96, and also displays information (for example, a message) indicating that the hub main body 48 identified from the hub ID 96 is unusable. If the determination unit 62C determines that the hub main body 48 is usable, the determination result screen 120 displays the hub ID 96, and also displays information (for example, a message) indicating that the hub main body 48 identified from the hub ID 96 is usable.

[0111] 11 shows an example in which the display control unit 62A outputs information for displaying the determination result on the display 42 (in the example shown in FIG. 11, a determination result screen 120), but the technology of the present disclosure is not limited to this. For example, the processor 62 of the management device 32 may output information for displaying the determination result to various presentation devices. In this case, for example, instead of or in addition to displaying the determination result on the display 42, the determination result may be output as audio by an audio playback device or recorded on a recording medium by a printer.

[0112] In the second embodiment, the processing performed by the display control unit 62A, the processing performed by the change unit 62B, and the processing performed by the determination unit 62C are examples of "processing using hub change characteristic information" according to the technology of the present disclosure.

[0113] Next, the operation of the hub management system 30 according to the second embodiment will be described with reference to FIG.

[0114] 12 shows an example of the flow of management processing performed by the processor 62 of the management device 32 according to the second embodiment. Note that the explanation here is based on the assumption that the hub-related information 94, the facility information 115, and the type information 116 are stored in the RFID tag 36.

[0115] 12, first, in step ST50, the decision unit 62C determines whether or not the hub-related information 114 has been received by the communication I / F 58. If the hub-related information 114 has not been received by the communication I / F 58 in step ST50, the decision is negative, and the management process proceeds to step ST62. If the hub-related information 114 has been received by the communication I / F 58 in step ST50, the decision is positive, and the management process proceeds to step ST52.

[0116] In step ST52, the determination unit 62C determines whether a condition for determining whether the hub main body 48 is usable (hereinafter referred to as a "hub main body usability determination condition") is satisfied using information other than the hub usability information 106 (i.e., information different from the hub usability information 106) included in the hub-related information 114 received by the communication I / F 58 in step ST50. Examples of the hub main body usability determination condition include a condition in which the reception device 40 receives an instruction to the determination unit 62C to determine whether the hub main body 48 is usable without using the hub usability information 106, or a condition in which the reception device 40 receives an instruction to prohibit the processor 62 from using the hub usability information 106.

[0117] In step ST52, if the hub main body usability determining condition is not satisfied, the determination is negative and the management process proceeds to step ST58. In step ST52, if the hub main body usability determining condition is satisfied, the determination is positive and the management process proceeds to step ST54.

[0118] In step ST54, the decision unit 62C decides whether or not the hub body 48 can be used based on the dimension information 100, quality information 102, usage history information 104, equipment information 115, and type information 116 included in the hub-related information 114 received by the communication I / F 58 in step ST50 (see FIG. 11). After the processing of step ST54 is executed, the management processing proceeds to step ST56.

[0119] In step ST56, the display control section 62A causes the display 42 to display the result determined by the determination section 62C in step ST54 (see FIG. 11). After the process of step ST56 is executed, the management process proceeds to step ST62.

[0120] In step ST58, the display control unit 62A generates the hub management screen 110 (see FIG. 6) based on the hub-related information 114 received by the communication I / F 58 in step ST50. After the processing of step ST58 is executed, the management processing proceeds to step ST60.

[0121] In step ST60, the display control section 62A causes the display 42 to display the hub management screen 110 generated in step ST58 (see FIG. 6). After the processing of step ST60 is executed, the management processing proceeds to step ST62.

[0122] In step ST62, the change unit 62B determines whether or not a change instruction from the administrator 43 has been accepted by the acceptance device 40. If the change instruction from the administrator 43 has not been accepted by the acceptance device 40 in step ST62, the determination is negative, and the management process proceeds to step ST68. If the change instruction from the administrator 43 has been accepted by the acceptance device 40 in step ST62, the determination is positive, and the management process proceeds to step ST64.

[0123] In step ST64, the change unit 62B generates a change instruction signal 112 (see FIG. 7) in accordance with the change instruction accepted in step ST62 by the accepting device 40. After the process of step ST64 is executed, the management process proceeds to step ST66.

[0124] In step ST66, the change unit 62B transmits the change instruction signal 112 generated in step ST64 to the RFID tag 36 via the reader / writer 34 (see FIG. 7). As a result, in the RFID tag 36, the change instruction signal 112 transmitted from the reader / writer 34 is received by the communication I / F 84. The processor 88 changes the content of the hub change characteristic information 98 in accordance with the change instruction signal 112 received by the communication I / F 84 (see FIG. 7). After the processing of step ST66 is executed, the management processing proceeds to step ST68.

[0125] In step ST68, the processor 62 determines whether or not the termination condition is satisfied. If the termination condition is not satisfied in step ST68, the determination is negative, and the management process proceeds to step ST50. If the termination condition is satisfied in step ST68, the determination is positive, and the management process ends.

[0126] As described above, in the hub management system 30, the usability of the hub main body 48 is determined based on the dimension information 100, quality information 102, usage history information 104, equipment information 115, and type information 116 contained in the hub-related information 114, and the determination result is displayed on the display 42. Therefore, the administrator 43 or the like can understand the result of the determination of the usability of the hub main body 48 based on the dimension information 100, quality information 102, usage history information 104, equipment information 115, and type information 116 contained in the hub-related information 114.

[0127] Furthermore, in the hub management system 30, the usability of the hub body 48 is determined in accordance with the dimension information 100 included in the hub-related information 114, and the determination result is displayed on the display 42. Therefore, the administrator 43 or the like can understand the result of the determination of the usability of the hub body 48 in accordance with the dimensions of the deformable portions included in the hub body 48.

[0128] Furthermore, in the hub management system 30, the usability of the hub main body 48 is determined in accordance with the quality information 102 included in the hub-related information 114, and the determination result is displayed on the display 42. Therefore, the administrator 43 or the like can understand the result of the determination of the usability of the hub main body 48 in accordance with the quality of the hub main body 48.

[0129] Furthermore, in the hub management system 30, the usability of the hub body 48 is determined in accordance with the expiration date information 102A included in the quality information 102, and the determination result is displayed on the display 42. Therefore, the administrator 43 or the like can understand the result of determining whether the hub body 48 is usable or not in accordance with the expiration date of the hub body 48.

[0130] Furthermore, in the hub management system 30, the usability of the hub main body 48 is determined in accordance with the usage history information 104 included in the hub-related information 114, and the determination result is displayed on the display 42. Therefore, the administrator 43 or the like can understand the result of the determination of the usability of the hub main body 48 in accordance with the usage history of the hub main body 48.

[0131] Furthermore, in the hub management system 30, whether or not the hub main body 48 can be used is determined in accordance with the facility information 115 included in the hub-related information 114, and the determination result is displayed on the display 42. Therefore, the administrator 43 or the like can understand the result of the determination of whether or not the hub main body 48 can be used in accordance with the facility that the hub main body 48 can be used with.

[0132] Furthermore, in the hub management system 30, the usability of the hub main body 48 is determined in accordance with the type information 116 included in the hub-related information 114, and the determination result is displayed on the display 42. Therefore, the administrator 43 or the like can understand the result of determining whether the hub main body 48 can be used in accordance with the type of magnetic tape MT that can be used with the hub main body 48.

[0133] In the second embodiment, the determination unit 62C determines whether the hub is usable based on at least one of the dimension information 100, the quality information 102, the usage history information 104, the equipment information 115, and the type information 116, regardless of the content of the hub usability information 106, and the determination result is displayed on the display 42. However, the technology of the present disclosure is not limited to this. For example, the determination unit 62C may determine whether the hub is usable based on the hub usability information 106 and display the result on the display 42. In this case, for example, the determination unit 62C determines whether the hub is usable based on at least one of the dimension information 100, the quality information 102, the usage history information 104, the equipment information 115, and the type information 116, and includes information indicating the determined hub usability as the hub usability information 106 in the hub change characteristic information 98. The display control unit 62A causes the display 42 to display the hub usability indicated by the hub usability information 106. Here, in addition to whether the hub can be used or not, the display 42 may also display, as reference information, the dimensions indicated by the dimension information 100, the quality indicated by the quality information 102, the usage history indicated by the usage history information 104, the equipment indicated by the equipment information 115, and the quality of the magnetic tape MT indicated by the type information 116.

[0134] In the above-described embodiments, an example has been described in which the hub management screen 110 and the determination result screen 120 are displayed on the display 42 of the management device 32, but the technology of the present disclosure is not limited to this. For example, if the reader / writer 34 is provided with a display, the hub management screen 110 and / or the determination result screen 120 may be displayed on the display of the reader / writer 34. Furthermore, at least one of the processes included in the above-described management process may be performed by the reader / writer 34.

[0135] Furthermore, in the above embodiment, an example has been described in which the management processing program 108 (118) is stored in the storage 64, but the technology of the present disclosure is not limited to this. For example, as shown in FIG. 13 , the management processing program 108 (118) may be stored in a portable storage medium 200 such as an SSD or a USB memory. The storage medium 200 is a computer-readable non-transitory storage medium. The management processing program 108 (118) stored in the storage medium 200 is installed in the computer 56 of the management device 32. The processor 62 executes management processing in accordance with the management processing program 108 (118).

[0139] The hardware resources for executing the management processes described in the above embodiments can be various processors, as listed below. Examples of processors include a CPU, which is a general-purpose processor that functions as a hardware resource for executing management processes by executing software, i.e., a program. Examples of processors include dedicated electrical circuits, such as FPGAs, PLDs, or ASICs, which are processors with a circuit configuration specifically designed to execute specific processes. Each processor has built-in or connected memory, and each processor executes management processes by using the memory.

[0140] The hardware resource that executes the management process may be configured with one of these various processors, or may be configured with a combination of two or more processors of the same or different types (for example, a combination of multiple FPGAs, or a combination of a CPU and an FPGA). Also, the hardware resource that executes the management process may be a single processor.

[0141] As an example of a system configured with a single processor, there is a first form in which one processor is configured by combining one or more CPUs and software, and this processor functions as a hardware resource that executes management processing. A second form, such as an SoC, uses a processor that realizes the functions of the entire system, including multiple hardware resources that execute management processing, on a single IC chip. In this way, management processing is realized using one or more of the above-mentioned various processors as hardware resources.

[0142] Furthermore, the hardware structure of these various processors can be, more specifically, an electric circuit that combines circuit elements such as semiconductor devices. The above management process is merely an example. Therefore, it goes without saying that unnecessary steps may be deleted, new steps may be added, or the processing order may be rearranged, without departing from the spirit of the present invention.

[0143] The above-described description and illustrations are a detailed explanation of the parts related to the technology of the present disclosure and are merely an example of the technology of the present disclosure. For example, the above description of the configuration, functions, actions, and effects is an explanation of an example of the configuration, functions, actions, and effects of the parts related to the technology of the present disclosure. Therefore, it goes without saying that unnecessary parts may be deleted, new elements may be added, or replacements may be made to the above-described description and illustrations within the scope of the gist of the technology of the present disclosure. Furthermore, in order to avoid confusion and to facilitate understanding of the parts related to the technology of the present disclosure, the above-described description and illustrations omit explanations of common technical knowledge that do not require particular explanation to enable the implementation of the technology of the present disclosure.

[0144] In this specification, "A and / or B" is synonymous with "at least one of A and B." In other words, "A and / or B" means that it may be only A, only B, or a combination of A and B. Furthermore, in this specification, the same concept as "A and / or B" is also applied when three or more things are expressed connected by "and / or."

[0145] All publications, patent applications, and technical standards mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication, patent application, or technical standard was specifically and individually indicated to be incorporated by reference.
