Optical disk jukebox batch file acquisition algorithm

Abstract

The invention relates to the technical field of optical disc jukeboxes, in particular to an optical disc jukebox batch file acquisition algorithm, which comprises the following steps of: Step 1, acquiring optical disc jukebox file attributes, and distinguishing files according to the optical disc jukebox file attributes; 2, when the optical disc jukebox file data are non-packaged files, non-packaged file features are obtained, file feature classification is carried out according to the non-packaged file features, and the files with the same category of features are subjected to feature arrangement; 3, when the optical disc jukebox file data is a packaged file, obtaining information of a disc box or an optical disc where the packaged file is located, and executing the information according to a non-packaged file processing logic; according to the technical scheme provided by the invention, the file obtaining efficiency is optimized to the greatest extent, the time of migration and switching of the optical discs and the disc boxes required for obtaining the files each time is shortened through grouping and sequencing the files, the influence on the service life when the optical disc library is frequently operated is reduced, the availability of the optical disc library is ensured, and the service life of the optical disc library is prolonged. Meanwhile, other operations are not affected, and the batch file obtaining efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of optical disc libraries, in particular to an algorithm for obtaining batch files of optical disc libraries. Background technique [0002] The CD-ROM library is a CD-ROM network sharing device with an automatic disk changer mechanism. The CD library is generally composed of three parts: the CD rack for placing the CD, the automatic disk changing mechanism and the drive. In recent years, as the storage capacity of a single optical disc has greatly increased, the price and performance advantages of optical disc libraries compared with common storage devices such as disk arrays and tape libraries have become more and more obvious. As a storage device, CD library has been gradually used in various fields, such as bank bill image storage, insurance institution data storage, and all other large-capacity near-line data storage occasions. [0003] However, in the prior art, it takes a long period of time to obtai...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides an algorithm for acquiring files in batches in the disc library, which solves the problem that each time a file is retrieved and extracted, the disc and the disc box will be migrated, and different files will be stored in the same disc. Or in the disk box, it will cause repeated migration of a CD or a disk box, and the result is a problem that greatly reduces the efficiency of obtaining files from the CD library.
