Optical disc library system and data reading and writing method for separating optical disc exchange and data storage

Abstract

The invention relates to the field of optical disk storage and provides an optical disk exchange and data storage separated optical disk jukebox system. The optical disk exchange and data storage separated optical disk jukebox system comprises a rear-end large-capacity optical disk jukebox and a front-end input-output optical disk jukebox which are connected with each other through a network bus. The rear-end large-capacity optical disk jukebox comprises a plurality of optical disk cabinets and rear-end controllers for controlling the optical disk cabinets. The optical disk cabinets are each composed of a plurality of optical disk boxes, and a plurality of optical disks are arranged in each optical disk box. The front-end input-output optical disk jukebox comprises a plurality of parallel CD drivers and front-end controllers for controlling the CD drivers. The optical disks in the CD drivers of the front-end input-output optical disk jukebox are in full-connection mapping relationship with the optical disks in the rear-end large-capacity optical disk jukebox. By means of the optical disk exchange and data storage separated optical disk jukebox system, data in the front-end input-out optical disk jukebox and data in the rear-end large-capacity optical disk jukebox are managed in a united mode, and the phenomenon that manual optical disk inserting and taking-out is low in efficiency and prone to error when data are directly read and written from the rear-end large-capacity optical disk jukebox in a data reading and writing process is avoided. Thus, efficient and intelligent management to a large optical disk jukebox is achieved.

Description

technical field

[0001] The invention belongs to the technical field of optical disk storage, and in particular relates to an optical disk library system and a data reading and writing method for separating optical disk exchange and data storage. Background technique

[0002] In the era of big data, the data growth rate continues to increase, which in turn puts enormous pressure on storage capacity and performance. More and more important data needs to be stored for a long time. For data that is not frequently accessed but needs to be stored for a long time, optical discs can be used for data storage. The advantage of optical disc media is that it has a long service life, and it can also ensure that data will not be lost in some extreme physical environments. Due to the increasing amount of data in this part, the capacity of a single disc is limited, so it is necessary to use a disc library to automatically store a large number of discs and manage disc data effectively. ...
