Description

Technical Field

[0002] Optical storage is a method of storing massive data using optical discs as storage media. It has the advantages of low energy consumption, portability, and long data retention period. It is very suitable for storing data with low access frequency and needs to be preserved for a long time.

[0003] Existing storage technologies mainly include three types of storage: magnetic hard disks, semiconductor USB flash drives (including SD cards), and optical disks. However, like magnetic storage and semiconductor storage, information will disappear when encountering strong electromagnetic fields, and information can be rewritten at any time; only optical storage can be read-only and cannot be rewritten after being written once. Therefore, optical storage is the safest, and optical disks have become an indispensable information carrier medium in today's information society.

[0004] At present, optical disk libraries have been gradually applied to many fields, such as bank bill image storage, insurance agency data storage, etc. However, existing optical disk libraries have some shortcomings, such as customers cannot easily transfer large amounts of data over long distances, storage capacity cannot be easily expanded, and data read and write speeds are still slow. Traditional array optical disk libraries are fixed in position and cannot be easily moved, and data read and write speeds are slow; cage optical disk libraries have small storage capacity and cannot be expanded according to actual storage requirements. With the rapid increase in the amount of information in various institutions, how to safely, conveniently and automatically manage and control this huge amount of information has become a top priority.
