How to store the explosively growing data has become an urgent problem to be solved. Blu-ray storage is a new type of optical storage technology. This technology can store a large amount of data through Blu-ray discs, and has the advantages of long storage life, low power consumption and low storage cost. By adopting a large number of Blu-ray discs, the above-mentioned explosively growing data can be stored, and the large number of Blu-ray discs can be managed by a disc library device. Specifically, the disc library device includes a mechanical arm, a plurality of optical disc drives and a large number of Blu-ray discs, and the plurality of optical disc drives are coupled to a server. Among them, the mechanical arm is used to put the Blu-ray disc that needs to be read and written into the corresponding optical disc drive, and the optical disc drive is used to communicate with the server to complete the reading and writing of the Blu-ray disc.

[0004] However, when the server needs to communicate with more optical disk drives, the scalability is poor and the implementation cost is high. Summary of the invention

[0011] Based on this solution, the first optical pickup unit is used to write data to the optical disc, or read data from the optical disc, the first processing circuit is used to process the data, and the Ethernet connector is used to transmit the data based on the Ethernet protocol, so that the optical disc drive can be coupled to the server through the Ethernet connector to achieve communication with the server. In the case where the server needs to communicate with more optical disc drives, compared with the solution in which the optical disc drive is coupled to the server through the serial advanced technology attachment interface, this solution does not require the server to set up multiple SAS cards or use more servers, thereby reducing the implementation cost. Secondly, compared with the solution in which the optical disc drive is coupled to the server through an external conversion board, this solution does not require the external conversion board to be set up, which can save space and reduce the implementation cost.

If the server needs to communicate with more optical disc drives, compared with the optical disc drive being coupled to the server through the Serial Advanced Technology Attachment interface and the optical disc drive being coupled to the server through an external conversion board, the expansion capability of the server to communicate with multiple optical disc drives can be improved, and the implementation cost can be reduced.

Specifically, the use of the words "exemplary" or "for example" is intended to present the related concepts in a concrete way.

[0058] Before introducing the embodiments of the present application, the technical terms and background technologies involved in the present application are first introduced.

[0059] Blu-ray storage: It is a new type of optical storage technology. By using large-capacity Blu-ray discs as data storage media, it has the technical advantages of long-term validity, non-tamperability, green energy saving, etc. Blu-ray storage technology is widely used in data backup systems, which can achieve data security storage with a validity period of more than 50 years, and the energy consumption of the data center is only 1 / 10 of that of traditional data centers.

[0060] Optical drive: abbreviated as optical drive, is a device used to read or write data on a CD.

[0061] Ethernet connector: A physical interface used to connect computers, network devices, and Ethernet cables, such as the registered jack 45 (RJ-45) connector, RJ-11 connector, Neil-Concelman bayonet (BNC) connector, and square connector (SC).

[0062] Serial advanced technology attachment (SATA) connector: is a physical interface used to connect storage devices such as hard drives, optical drives, and solid state drives (SSDs).

[0063] Field-programmable gate array (FPGA): FPGA is a product further developed on the basis of programmable array logic (PAL) devices, generic array logic (GAL) devices, complex programmable logic devices (CPLD) and other programmable devices. FPGA is a semi-custom circuit in the field of application specific integrated circuit (ASIC), which solves the shortcomings of custom circuits and overcomes the shortcomings of the limited number of gate circuits of the original programmable devices.

[0064] System on a chip (SOC): It can also be called the main control chip. In the optical drive, SOC is used for analog processing (amplification, filtering, equalization, etc.) and digital processing (pattern recognition and machine learning (PRML)), as well as encoding and decoding of signals. Among them, digital processing refers to the application of some algorithms and techniques in PRML to digital signal processing to achieve tasks such as digital signal acquisition, preprocessing, feature extraction, classification and recognition. SOC is also used to perform high-precision focusing and tracking control on the read and write beams of the optical pick-up unit (OPU) to achieve reading and writing of optical discs.

[0065] Optical pickup unit: used to read and write data from optical storage discs such as Blu-ray discs, digital video discs (DVDs) and compact disks (CDs). Specifically, when writing data, the SOC is used to send an electrical signal carrying data to the optical pickup unit, and the optical pickup unit can generate an optical signal based on the electrical signal and transmit the optical signal to the optical disc, thereby writing data to the optical disc. When reading data, the optical pickup unit is used to transmit an optical signal to the optical disc, receive the optical signal reflected from the optical disc, convert the reflected optical signal into an electrical signal and send it to the SOC, which analyzes the electrical signal to obtain data.

[0066] Multiplexing: refers to the technology of combining multiple data into one data for transmission. This technology allows multiple data to share the same channel for transmission, thereby effectively utilizing bandwidth resources and improving transmission efficiency. Multiplexing methods include frequency division multiplexing (FDM), time division multiplexing (TDM) and wavelength division multiplexing (WDM).

[0067] Demultiplexing: refers to the process of decomposing data merged through multiplexing technology into original data.

[0068] Ethernet switching (SW) chip: a chip used for Ethernet interface that can combine multiple Ethernet interfaces into a switch to achieve data exchange and transmission.

[0069] Currently, the optical disc drive in the optical disc library device generally provides a serial advanced technology attachment interface, through which the optical disc drive can be coupled to the server, or can first be coupled to an external conversion board through the serial advanced technology attachment interface, and then coupled to the server through the Ethernet interface of the external conversion board. Thus, the server can communicate with the optical disc drive and read or write data in the optical disc through the optical disc drive.

[0070] For example, Figure 1 As shown in (a), it is a schematic diagram of the structure of an optical disc drive 110. The optical disc drive 110 includes a serial advanced technology attachment connector 111, an FPGA 112, a first SOC 113, a second SOC 114, a first OPU 115, and a second OPU 116. The FPGA 112 is coupled to the serial advanced technology attachment connector 111 through a first serial advanced technology attachment interface, the FPGA 112 is coupled to a first end of the first SOC 113 through a second serial advanced technology attachment interface, the FPGA 112 is coupled to a first end of the second SOC 114 through a third serial advanced technology attachment interface, the second end of the first SOC 113 is coupled to the first OPU 115, and the second end of the second SOC 114 is coupled to the second OPU 116.

[0071] Among them, the first OPU 115 is used to read and write the first data in the optical disc, the first SOC 113 is used to process the first data, and the first OPU 115 and the first SOC 113 constitute a first channel. The second OPU 116 is used to read and write the second data in the optical disc, the second SOC 114 is used to process the second data, and the second OPU 116 and the second SOC 114 constitute a second channel. The FPGA 112 is used to multiplex or demultiplex the first data and the second data to achieve a balance of business loads between the first channel and the second channel. The serial advanced technology attachment connector 111 is used to transmit the multiplexed first data and the second data based on the serial advanced technology attachment protocol. For the specific data processing process, reference can be made to the prior art, and the embodiments of the present application will not be repeated here.

[0072] When multiple optical disk drives 110 communicate with the server 120, Figure 1 As shown in (b), the multiple optical disk drives 110 can be coupled to a serial attached small computer system interface (SAS) card 121 in the server 120 through a serial advanced technology attachment connector 111, so as to realize the communication between the multiple optical disk drives 110 and the server 120. Or, as Figure 1 As shown in (c), the multiple optical disk drives 110 can first be coupled to the external conversion board 130 through the SATA connector 111, and the external conversion board 130 can include an advanced reduced instruction set computing machine (ARM) chip, and the ARM chip can be used to convert Ethernet protocol data and SATA protocol data. Then, the external conversion board 130 is coupled to the switch 140 through the Ethernet interface of the external conversion board 130. Finally, the switch 140 is coupled to the server 120 to realize the communication between the multiple optical disk drives 110 and the server 120.

[0073] However, when the optical drive 110 is coupled to the server 120 through the SAS card 121 to achieve communication with the server 120, since the number of interfaces of the SAS card 121 is limited, if the server 120 needs to be coupled to more optical drives 110 to achieve communication with more optical drives 110, more SAS cards 121 need to be set in the server 120, or more servers 120 need to be coupled to the optical drive 110. Therefore, the use of this communication method will result in poor expansion capability of the server 120 coupled to multiple optical drives 110, and high implementation cost. When the optical drive 110 is coupled to the server 120 through the external conversion board 130 and the switch 140 to achieve communication with the server 120, since the external conversion board 130 needs to occupy additional space and the cost of the external conversion board 130 is high, the implementation cost will be high. If the server 120 needs to be coupled to more optical drives 110 to achieve communication with more optical drives 110, more external conversion boards 130 are needed, and more space is needed. Therefore, the use of this communication method will also result in poor expansion capability of coupling the server 120 with multiple optical disk drives 110 and higher implementation costs.

[0074] In summary, when the optical disc drive is coupled to the server through the SATA interface, or is first coupled to the external conversion board through the SATA interface and then coupled to the server through the Ethernet interface of the external conversion board to achieve communication with the server, if the server needs to communicate with more optical disc drives, there are problems of high implementation cost and poor server expansion capability. In order to solve this problem, an embodiment of the present application provides an optical disc drive, which provides an Ethernet interface, so that it can be coupled to a switch through the Ethernet interface, and then coupled to the server through the switch to achieve communication with the server. Since the switch has more ports than the SAS card, the expansion capability of the server to communicate with multiple optical disc drives can be improved, and the implementation cost can be reduced.

[0075] like Figure 2 As shown in (a), the optical disc drive 200 provided in the embodiment of the present application can be used as an independent device, and the electronic device 300 can be coupled to the optical disc drive 200, so that the electronic device 300 can read data from the optical disc through the optical disc drive 200, or write data to the optical disc. Optionally, the electronic device 300 may include but is not limited to: a server, a laptop computer, a desktop computer, an industrial computer and a smart TV, which is not limited in the embodiment of the present application. Among them, a server refers to a special-purpose computer with higher computing power than an ordinary computer, and the server can be a file server, a database server, an application server and other types of servers, which are not limited in the embodiment of the present application.

[0076] like Figure 2 As shown in (b), the optical disc drive 200 provided in the embodiment of the present application can also be used as a hardware device in the electronic device 300, coupled with the mainboard 310 in the electronic device 300, so that the electronic device 300 can read data from the optical disc or write data to the optical disc through the optical disc drive 200.

[0077] like Figure 2 As shown in (c), when the optical disc drive 200 is used as a hardware device in the electronic device 300, the electronic device 300 may be an optical disc library device 300, and the optical disc library device 300 includes a mechanical arm 320, an optical disc 330, and the optical disc drive 200. The mechanical arm 320 is used to put the optical disc 330 into the optical disc drive 200, and the optical disc drive 200 is used to write data to the optical disc 330, or read data from the optical disc 330.

[0078] Optionally, the optical disc library device 300 may include multiple optical discs 330 and multiple optical disc drives 200. The embodiment of the present application does not limit the specific number of optical discs 330 and optical disc drives 200 included in the optical disc library device.

[0079] like Figure 3 As shown, the optical disc drive 200 provided in the embodiment of the present application can also be applied to an optical disc library system 400. The optical disc library system 400 includes a server 410, a switch 420 and an optical disc library device 300, and the optical disc library device 300 includes a plurality of optical disc drives 200. The plurality of optical disc drives 200 can communicate with the server 410 through the switch 420, so that the server 410 can read data from an optical disc through the plurality of optical disc drives 200, or write data to an optical disc.

[0080] like Figure 4 , which is a schematic diagram of the structure of an optical disc drive 200 provided in an embodiment of the present application. The optical disc drive 200 includes an Ethernet connector 210, a first processing circuit 220, and a first OPU 230 coupled in sequence. The first OPU 230 is used to write data to the optical disc, or read data from the optical disc, the first processing circuit 220 is used to process the data, and the Ethernet connector 210 is used to transmit the data based on the Ethernet protocol.

[0081] Thus, the optical drive 200 can be coupled to the Ethernet interface in the server through the Ethernet connector 210, and can communicate with the server through the Ethernet connector 210. When the server needs to communicate with multiple optical drives 200, the multiple optical drives 200 can be coupled to the switch through the Ethernet connector 210 respectively, and then coupled to the server through the Ethernet interface of the switch. It can be understood that by adopting the optical drive 200, when the server needs to communicate with more optical drives, compared with the above-mentioned optical drive coupled to the server through the serial advanced technology attachment interface, the server does not need to set up multiple SAS cards, or adopt more servers, which can reduce the implementation cost. Secondly, compared with the above-mentioned optical drive coupled to the server through an external conversion board, it is not necessary to set up an external conversion board, which can save space and reduce the implementation cost. Moreover, since the switch has more ports than the SAS card, the server can be coupled to more optical drives 200 through the switch, which can improve the expansion capability of the server to communicate with multiple optical drives 200.

[0082] Optionally, the Ethernet connector 210 may be an optical Ethernet connector, or may be an electrical Ethernet connector, which is not limited in the embodiments of the present application.

[0083] Optionally, the Ethernet connector 210 may support at least one of a Gigabit Ethernet (GE) communication rate, a 2.5 Gigabit Ethernet per second (2.5G) communication rate, and a 10 Gigabit Ethernet per second (10GE) communication rate, and the embodiments of the present application do not limit this.

[0084] In a possible embodiment, the first processing circuit 220 may be a SOC, which is not limited in the embodiment of the present application.

[0085] Optionally, the first OPU 230 may be used to read and write optical storage discs such as Blu-ray discs, DVDs or CDs, which is not limited in the embodiment of the present application.

[0086] In the optical disc drive 200 provided in the embodiment of the present application, the first OPU 230 is used to write data to the optical disc, or read data from the optical disc, the first processing circuit 220 is used to process the data, and the Ethernet connector 210 is used to transmit the data based on the Ethernet protocol, so that the optical disc drive 200 can be coupled to the server through the Ethernet connector 210 to achieve communication with the server. In the case where the server needs to communicate with more optical disc drives, compared with the solution in which the optical disc drive is coupled to the server through the serial advanced technology attachment interface, this solution does not require the server to set up multiple SAS cards or use more servers, thereby reducing the implementation cost. Secondly, compared with the solution in which the optical disc drive is coupled to the server through an external conversion board, this solution does not require the external conversion board to be set up, which can save space and reduce the implementation cost. Moreover, since the switch has more ports than the SAS card, the server in this solution can be coupled to more optical disc drives 200 through the switch, which can improve the expansion capability of the server to communicate with multiple optical disc drives 200.

[0087] like Figure 5 As shown, in a possible embodiment, the optical disk drive 200 further includes a second processing circuit 240. The second processing circuit 240 is coupled to the Ethernet connector 210 via a first Ethernet interface, and the second processing circuit 240 is coupled to the first processing circuit 220 via a first STAIA interface.

[0088] The second processing circuit 240 is used to convert Ethernet protocol data and SATA protocol data.

[0089] For example, the second processing circuit 240 may receive SATA data sent by the first processing circuit 220 , convert the data into Ethernet data, and then send the Ethernet data to the Ethernet connector 210 .

[0090] For another example, the second processing circuit 240 may receive Ethernet protocol data sent by the Ethernet connector 210 , convert the data into SATA protocol data, and then send the SATA protocol data to the first processing circuit 220 .

[0091] Optionally, the first Ethernet interface of the second processing circuit 240 can support at least one of the communication rates of Gigabit Ethernet, 2.5 Gigabit Ethernet per second, and 10 Gigabit Ethernet per second, which is not limited in the embodiments of the present application.

[0092] In a possible embodiment, the second processing circuit 240 may be an FPGA, which is not limited in the embodiment of the present application.

[0093] The optical disc drive 200 provided in the embodiment of the present application is provided with a second processing circuit 240 between the Ethernet connector 210 and the first processing circuit 220, and the data of the Ethernet protocol and the data of the Serial Advanced Technology Attachment protocol are mutually converted by the second processing circuit 240, so that the optical disc drive 200 can be coupled with the server through the Ethernet connector 210 to achieve communication with the server. In the case where the server needs to communicate with more optical disc drives, compared with the solution in which the optical disc drive is coupled with the server through the Serial Advanced Technology Attachment interface, this solution does not require the server to set up multiple SAS cards or use more servers, thereby reducing the implementation cost. Secondly, compared with the solution in which the optical disc drive is coupled with the server through an external conversion board, this solution does not require the external conversion board to be set up, which can save space and reduce the implementation cost. Moreover, since the switch has more ports than the SAS card, the server in this solution can be coupled with more optical disc drives 200 through the switch, which can improve the expansion capability of the server to communicate with multiple optical disc drives 200.

[0094] The first processing circuit 220 and the first OPU 230 constitute a channel. In addition to this channel, the optical disc drive 200 may also include multiple channels. The embodiment of the present application does not limit this. The embodiment of the present application takes the optical disc drive 200 including two channels as an example for illustrative description.

[0095] like Figure 6 As shown, in a possible implementation, the optical disc drive 200 further includes a third processing circuit 250 and a second OPU 260 coupled to each other, wherein the third processing circuit 250 and the second OPU 260 form a channel. The second processing circuit 240 is coupled to the third processing circuit 250 via a second STA.

[0096] In a possible embodiment, the third processing circuit 250 may be a SOC, which is not limited in the embodiment of the present application.

[0098] Optionally, the first OPU 230 and the second OPU 260 may be used to read and write the same type of optical storage optical discs, or may be used to read and write different types of optical storage optical discs, which is not limited in the embodiments of the present application.

[0099] For example, the first OPU 230 can be used to read and write a Blu-ray disc, and the second OPU 260 can be used to read and write a CD, thereby improving the compatibility of the optical disc drive 200 .

[0100] For another example, the first OPU 230 and the second OPU 260 can both be used to read and write a Blu-ray disc, thereby improving the efficiency of reading and writing data by the optical disc drive 200. Moreover, when any one of the two optical pickup units fails, the optical disc drive 200 can continue to work, thereby improving the reliability of the optical disc drive 200. In the following embodiments of the present application, the first OPU 230 and the second OPU 260 are used to read and write the same type of optical storage disc for exemplary description.

[0101] In a possible embodiment, when the server writes data into the optical disc through the optical disc drive 200:

[0102] The Ethernet connector 210 is specifically configured to receive the multiplexed first data and second data based on the Ethernet protocol.

[0103] The second processing circuit 240 is specifically configured to demultiplex the multiplexed first data and second data, convert both the first data and the second data into SATA data, and send the first data to the first processing circuit 220 and send the second data to the third processing circuit 250 .

[0104] The first processing circuit 220 is specifically configured to encode the first data and send the encoded first data to the first OPU 230 .

[0105] The first OPU 230 is specifically used to write the encoded first data into the optical disc.

[0106] The third processing circuit 250 is specifically configured to encode the second data and send the encoded second data to the second OPU 260 .

[0107] The second OPU 260 is specifically used to write the encoded second data into the optical disc.

[0108] In a possible embodiment, when the server reads data from the optical disc through the optical disc drive 200:

[0110] The first processing circuit 220 is specifically configured to decode the encoded third data and send the third data to the second processing circuit 240 based on the SATA protocol.

[0111] The second OPU 260 is specifically used to read the encoded fourth data from the optical disc.

[0112] The third processing circuit 250 is specifically configured to decode the encoded fourth data and send the fourth data to the second processing circuit 240 based on the SATA protocol.

[0113] The second processing circuit 240 is specifically configured to convert the third data and the fourth data into Ethernet protocol data, multiplex the third data and the fourth data, and send the multiplexed third data and the fourth data to the Ethernet connector 210 .

[0114] The Ethernet connector 210 is specifically used to send the multiplexed third data and fourth data based on the Ethernet protocol.

[0115] The optical disc drive 200 provided in the embodiment of the present application forms a channel by setting a third processing circuit 250 and a second OPU 260. When the second OPU 260 and the first OPU 230 are used to read and write the same type of optical storage optical discs, the reading and writing efficiency and reliability of the optical disc drive 200 can be improved. When the second OPU 260 and the first OPU 230 are used to read and write different types of optical storage optical discs, the compatibility of the optical disc drive 200 can be improved.

[0116] In a possible embodiment, Figure 6 As shown, the optical disk drive 200 further includes a first STA connector 270, and the second processing circuit 240 is coupled to the first STA connector 270 via a STA interface. The first STA connector 270 is used to transmit data of the STA protocol.

[0117] Thus, the optical disc drive 200 can also be coupled to the server through the first SATA connector 270, which can make the coupling mode between the optical disc drive 200 and the server more flexible. When the optical disc drive 200 is coupled to the server through the first SATA connector 270, the second processing circuit 240 is used to transmit the SATA protocol data received from the first SATA connector 270 to the first processing circuit 220 and the third processing circuit 250, or transmit the SATA protocol data received from the first processing circuit 220 and the third processing circuit 250 to the first SATA connector 270. It can be understood that when the optical disc drive transmits data through the first SATA connector 270, the second processing circuit transmits the SATA protocol data as a path, and does not perform protocol conversion on the data.

[0118] The optical disc drive 200 provided in the embodiment of the present application can be coupled to a server through the first SATA connector 270 by providing a first SATA connector 270, so that the coupling mode between the optical disc drive 200 and the server can be more flexible.

At this time, the first processing circuit 220 can be used to implement the functions implemented by the first processing circuit 220 and the second processing circuit 240, and the embodiment of the present application will not be repeated here. It can be understood that at this time, the first processing circuit 220 is coupled to the Ethernet connector 210 through the Ethernet interface.

[0120] Optionally, the Ethernet interface of the first processing circuit 220 may support at least one of a Gigabit Ethernet communication rate, a 2.5 Gigabit Ethernet communication rate per second, and a 10 Gigabit Ethernet communication rate per second, which is not limited in the embodiments of the present application.

[0121] In a possible embodiment, the first processing circuit 220 and the second processing circuit 240 may be integrated into one chip, such as a SOC.

[0122] In a possible embodiment, Figure 7 As shown in (b) of FIG. 1 , when the first processing circuit 220 and the second processing circuit 240 are one processing circuit, and the processing circuit is the first processing circuit 220, the optical disc drive 200 may further include a second STA connector 280, and the first processing circuit 220 may be coupled to the second STA connector 280 via a STA interface. The second STA connector 280 is used to transmit data of a STA protocol. Thus, the optical disc drive 200 may also be coupled to a server via the second STA connector 280, which may make the coupling method between the optical disc drive 200 and the server more flexible.

[0123] In a possible embodiment, the first processing circuit 220 and the first OPU 230 constitute a channel, and the optical disc drive 200 may include multiple channels.

[0137] The Ethernet switching circuit 290 is used to forward the fifth data to the first processing circuit 220. The first processing circuit 220 is specifically used to encode the fifth data and send the encoded fifth data to the first OPU 230. The first OPU 230 is specifically used to write the encoded fifth data into the optical disc.

[0138] Alternatively, the Ethernet switching circuit 290 is used to forward the fifth data to the fourth processing circuit 2100. The fourth processing circuit 2100 is used to encode the fifth data and send the encoded fifth data to the third OPU 2110.
