Manipulator with rotatable tray, optical disc library and storage and retrieval method thereof

Abstract

The invention relates to the field of data storage, and discloses a manipulator with a rotatable tray, which includes a bracket body and a tray gripper arranged on the bracket body. The robot arm also includes a rotating tray and a tray driving mechanism. The catcher, the rotary tray is used to support the optical disc, the rotary tray has a retracted state and an extended state, and the tray driving mechanism is used to drive the rotary tray to switch between the retracted state and the extended state. Also disclosed are an optical disc library with the manipulator and a disk storage and retrieval method based on the optical disc library. The disc library based on the manipulator with rotatable trays of the present invention has simple structure and convenient operation, not only improves the storage capacity of the optical discs in the optical disc library, but also improves the physical isolation of the database, realizes the safe storage of optical disc data, and has wide applications prospect.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a manipulator with a rotatable tray, an optical disk library and a disk storage and retrieval method. Background technique [0002] The optical disc library is a mass data storage device that uses standardized optical discs as the data storage medium, and is used for long-term or permanent storage of data information. With the rapid development of the information age, information security work is particularly important. The essence of information security is to protect important information resources from various types of threats, interference and destruction, that is, to ensure the security of information. Information security is an issue that any country, government, department, or industry must attach great importance to, and it is a national security strategy that cannot be ignored. [0003] Information may be leaked during the process of storage, reading and writing, and disc re...

AI Technical Summary

Problems solved by technology

[0003] Information may be leaked during the process of storage, reading and writing, and disc retrieval. In the traditional optical disc library, the manipulator is designed outside the optical disc library. Move the lower rail to the front of the magazine storing the target disc, pull out the magazine and grab the target disc in the magazine, that is, the opening of the traditional disc library to access the disc is within the reach of the human hand, and the disc library can be directly accessed by the human hand Obviously, such a CD-ROM library does not have isolation, and the CDs in the CD-ROM library are vulnerable to manual operation, leading to information security accidents.

[0004] However, isolating the disc library from human hands will cause problems in storing and retrieving discs. To set up a disc retrieval mechanism inside the optical disc library to send the discs in the optical disc library out of the optical disc library, it is necessary to consider the spatial structure of the optical disc magazine in the optical disc library. The current large-scale optical disc library cannot realize the storage, retrieval and reading and writing of optical discs in the optical disc library without affecting the magazine structure of the optical disc library while ensuring that the optical discs in the optical disc library cannot be touched by human hands. operate
