A method for recovering optical discs by using a disc grabber with double-layer inserts in an optical disc library

Abstract

The invention discloses a method for recovering optical discs in an optical disc library by using a disc grabber with double-layer inserts. The method sorts the positions of the optical discs in the optical disc case, and compares the position number of the optical disc in the optical disc case with the target where the optical disc is located. The number of the tray is linked, and the position number of the disc in the original disc box is automatically matched according to the number of the target tray, and the number of discs that need to be moved to put the disc back to the original physical position is obtained through calculation, and then the disc is put back to the original position. The invention does not change the stacking order of the optical discs in the optical disc box, and does not need to update the database information after the disc changing operation, increases the stability of the database, reduces the computing load of the controller, and optimizes the optical disc library management system.

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
