A device, method and system for data storage and reading and writing based on off-line optical disc library

Abstract

The invention discloses data storage and read-write equipment based on an off-line optical disk jukebox, a method and a system. the equipment contains multiple off-line optical disk jukeboxes and an off-line optical disk jukebox operating device. Several optical disk cartridge bins are configured inside an optical disk jukebox body of each off-line optical disk jukebox. Several optical disk cartridges for storing optical disks are configured inside each optical disk cartridge bin. The off-line optical disk jukeboxes store optical disk data with no power supply. The off-line optical disk jukebox operating device can movably access each of the multiple off-line optical disk jukeboxes, electrifies corresponding off-line optical disk jukebox and finishes storage and read operations of data. The equipment provided by the invention can finish numerous functions such as automatic loading, parallel read-write, automatic detection, automatic disk printing and the like of optical disks.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to a device, method and system for storing and reading offline optical disc library data. Background technique [0002] The optical disc library is a mass data storage device that uses standardized optical discs as data storage media. The optical disk library is connected with the computer through the data communication interface, and the data on all the optical disks in the optical disk library can be automatically provided to the user according to the demand through the management software of the optical disk library. At the same time, users can also easily write data to the discs in the disc library. Therefore, optical disc libraries are widely used in long-term archiving and preservation of data. [0003] The offline optical disc library is an intelligent storage device for long-term storage of data optical discs. The optical disc magazine in the offline opti...

It is difficult to take into account the needs of these two stages in the design of the system

In the scheme design with high technical index requirements, only the hardware configuration in the "writing" stage can be improved, resulting in a waste of hardware resources in the "reading" stage. Considering that the "writing" stage only accounts for The beginning is very small, so this contradiction is particularly prominent
