Abstract

The invention discloses an optical disk library array comprising optical disk library modules. Each of the optical disk library modules comprises an optical disk cassette, a drive, a manipulator assembly and a drive control unit. The optical disk library array comprises a plurality of optical disk library modules, an optical disk library server, a high-speed data interface unit and a control lumped unit, wherein the high-speed data interface unit and the control lumped unit are respectively connected with the optical disk library server; the drive of each optical disk library module is connected with the high-speed data interface unit through a data flow channel; and the drive control unit of each optical disk library module is connected with the control lumped unit through a control signal channel. The invention can greatly improve the read-write speed of the whole optical disk storage system and improve the reliability, the fault tolerance and the rapid recovery capability of the system to a certain extent.

Description

technical field [0001] The invention relates to an optical disc library array. Background technique [0002] Optical disc library is a mass data storage device that uses standardized optical discs as data storage media, and is widely used for long-term and permanent storage of data. The principle structure of a typical commercialized and modularized optical disc library is as follows: figure 1 shown. figure 1 The optical disc library 1 in the disc is composed of a disc magazine 2, an optical drive 3, a manipulator assembly for transferring the optical disc 8 between the disc magazine 2 and the optical drive 3, a motor drive control unit and an optical disc mailbox. Wherein the manipulator assembly includes the manipulator drawer 4, the manipulator grabber 5 and the manipulator lifter 6, the manipulator drawer 4 and the manipulator grabber 5 can rise and fall along with the manipulator lifter 6, and the manipulator drawer 4 is used for pulling and pushing the optical disc ...
