Method for taking back optical disk through disk grabbing device with double layers of insertion pieces in optical disk library

Abstract

The invention discloses a method for taking back an optical disk through a disk grabbing device with double layers of insertion pieces in an optical disk library. According to the method, position sorting is carried out on optical disks in an optical disk box, the relationship between the position serial numbers of the optical disks in the optical disk box and the serial numbers of target trays where the optical disks are located is built, the position serial number of one optical disk is obtained automatically through matching according to the serial number of the corresponding target tray, the number of optical disks which need to be moved for placing the optical disk back to the original physical position is obtained through calculation, and thus the optical disk is placed back to the original position. According to the method, the stacking sequence of the optical disks in the optical disk box is not changed, database information does not need to be updated after disk replacement operation is carried out, the stability of a database is improved, the operation load of a controller is reduced, and an optical disk library management system is optimized.

Description

technical field [0001] The invention relates to the carrying of optical discs in an optical disc library, in particular to a method for recovering optical discs in an optical disc library using a disk grabber with double-layer inserts. 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 is automatically provided to the user 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. Existing disc library includes disc box, optical drive, manipulator and controller etc., and manipulator comprises disc extractor, disc gripper and displacemen...

AI Technical Summary

Problems solved by technology

[0012] Although the above-mentioned method solves the problem of grabbing any disc from multiple discs, it also provides a method for recovering discs, that is, based on the powerful processing function of the controller in the disc library and the convenience of operation, it is easy to think of The processed discs are directly stacked on multiple discs, and the controller records each action, and updates the information in the database according to the order of the discs; although this method is feasible to a certain extent, the requirements for the controller High, so that the calculation load is heavy. Once one of the records is wrong, the data in the database will be incomplete; in addition, in the case of power failure, program freezing, etc., the data is also very easy to lose. Once the data is lost, Just need to carry out comprehensive scanning to all discs in the disc library, at this time the disc library has to be deactivated, taking up manpower and time; thus the way of putting the processed discs directly on multiple discs without putting them back in place is Poor
