Mass optic disc offline storage system and method for automatic and quick positioning of optic disc data

The invention is suitable for the technical field of data storage, and provides a mass optic disc offline storage system and a method for automatic and quick positioning of optic disc data. The method comprises the following steps of establishing an address mapping table; when a read-write operation instruction is received, analyzing the operation instruction to obtain the logic address; finding the address mapping table; when the logic address exists, obtaining the corresponding physical address; generating the corresponding control instruction according to the physical address, analyzing and transferring, and finally controlling an optic disc offline cabinet indication light, a disc cabinet drawer indication light and an optic disc drawer indication light to come on. By adopting the technical scheme, the system has the advantages that the locations of required data are found without manual interference; after the corresponding physical address is obtained by finding the mapping table, the location of the re
