Abstract
Description
Technical Field
[0001] The present invention relates to an optical disc storage system, and in particular to an optical disc cartridge with semiconductor storage, a storage system and a file reading and writing method. Background Art
[0002] Optical discs have always been one of the important carriers for long-term data storage due to their own safe and stable storage characteristics. In actual use, in order to avoid the disadvantages of limited capacity and easy damage of a single optical disc, multiple optical discs are usually placed in a storage device, namely an optical disc cartridge, and each optical disc cartridge has a unique ID number. In this way, when the server wants to read a certain file, it must first find the corresponding optical disc cartridge and the corresponding optical disc in the cartridge from the directory established inside the server, and then find the file by reading the file directory of the optical disc.
[0003] The above storage mechanism is more suitable for large optical disk storage systems with relatively fixed optical disk cartridges. However, when the optical disk cartridge needs to be operated remotely, for example, when the optical disk cartridge needs to be taken out from one storage system and put into another storage system for access, since the optical disks and file directories in the optical disk cartridge are stored in the previous storage system, the new storage system needs to scan all the optical disks in the optical disk cartridge and rebuild the file directory. Since reading multiple optical disks is a complicated and tedious mechanical action process, it generally takes a long time. The complicated process is shown in FIG. Figure 1 In addition, even if the optical disc cartridge is returned to the original storage system, since the files on the optical disc have been added or deleted by other storage systems, the file directory previously stored in this storage system is no longer accurate, and the only way is to scan all the optical discs again to update the file directory. It can be seen that the current optical disc storage solution is very inconvenient for optical disc cartridges to move between different storage systems. Summary of the invention
[0004] In view of the technical problem that it takes too long to rescan the contents of the optical disc to create a directory when the optical disc cartridge is used in different storage systems, a disc cartridge with semiconductor storage, a storage system and a file reading method are provided. The present invention sets an independent semiconductor storage device on the optical disc cartridge, and uses the device to store the file directory of the optical disc cartridge, so that when the optical disc cartridge is used in different storage systems, the file directory in the semiconductor storage device can be directly called to achieve fast search. At the same time, when the file storage changes, the directory information in the semiconductor storage device can be updated without the need for the optical disc storage system to update the entire directory, thereby improving the convenience of using the optical disc cartridge.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0039] Example 1

The housing 2 has a hollow accommodation space; the optical disc array 1 is arranged in the middle of the hollow accommodation space of the housing, and the optical disc array is arranged in an upper and lower hierarchical structure, and each hierarchical structure accommodates a disc. The semiconductor storage medium is arranged at the edge of the housing and has an interface 4, which is connected to an external system through a window 3 on the side of the housing.
[0041] Specifically, in addition to the space for accommodating the optical disc array, the inside of the optical disc cartridge housing 2 is also provided with a space for placing a semiconductor storage medium, and corresponding protection measures are provided to prevent the storage medium from being physically damaged. The semiconductor storage medium is used to store directory information of files stored on the optical discs in the optical disc cartridge.
[0042] Preferably, in the present invention, the optical disc cartridge housing adopts a rectangular parallelepiped structure, the optical disc array is arranged in the middle of the accommodating space, and the semiconductor storage medium is arranged at the edge position, and the two do not contact each other in the spatial structure.

Specifically, the semiconductor storage medium is embedded in the housing and is openly connected to the external metal bump through the window.
[0043] Semiconductor storage medium: According to the amount of data to be stored and the access speed requirements, a suitable semiconductor storage medium is selected. The optional semiconductor storage media include EEPROM, Flash, SRAM, DRAM, etc.
[0044] In the present invention, the semiconductor storage medium is used to store a directory file to facilitate tracking and management of all data stored in the optical disc cartridge.

The optical disc reading device also includes a user interface for receiving commands input by a user and displaying operation results.
[0054] Example 3
[0055] Based on Example 2, this embodiment provides a file reading and writing method, which is implemented based on the above storage system and includes the following steps:
[0056] S101, starting a main control device, initializing various components of an optical disc reading device, and obtaining an operation instruction, wherein the operation instruction includes reading and writing content stored in an optical disc or reading and writing content stored in a semiconductor storage medium;

[0058] If the semiconductor storage medium content is to be read and written, the main control device controls the optical disc cartridge transport device to move the designated optical disc cartridge to the reading position of the read-write device, the main control device activates the read-write device and locates the semiconductor storage medium interface, and the read-write device reads and writes the file directory data on the semiconductor storage medium through the metal conductive contacts;

[0061] Based on Example 2, this example provides a file reading method, such as Figure 4 As shown, the following steps are included:
[0062] S201, inserting the optical disc cartridge into the optical disc cartridge support of the storage system, and connecting the optical disc cartridge with the interface through the metal bump. Specifically, the metal bump on the optical disc support is connected to the mainboard interface of the storage system through a data connection line. The mainboard interface can be a universal interface, such as USB, or a custom interface.
[0063] S202, reading the information of the storage directory of each optical disc and file in the current optical disc cartridge semiconductor storage medium. Specifically, data communication is performed through a general protocol or a proprietary protocol according to the type of the interface between the mainboard and the semiconductor storage medium of the optical disc cartridge.
[0064] S203: Update the file directory of the storage system based on the read information about the optical discs and file storage directory of the current optical disc cartridge.
[0065] S204: Search for and read files based on the updated file directory.
[0066] Compared with the current storage system's mechanism for importing the file directory of the CD-ROM cartridge, the efficiency of establishing the CD-ROM file directory has been greatly improved from mechanically scanning each CD to simply reading information from the semiconductor. For example, it takes 30 seconds to scan each CD, and if a CD-ROM cartridge has 12 CDs, then the time saved is about 6 minutes.
