Rotary optical disc storage device, optical disc juke-box and magneto-optical converged storage device

Abstract

The invention relates to the field of data storage and discloses a rotary disc storage device. The device comprises a rotatable juke-box body. A multi-layer s arranged inside the juke-box body. Along the circumferential direction, each layer of the disc holder is provided with a set of optical disc accommodation lattices. The openings of the accommodation lattices are arranged towards the outside. The optical disc accommodation lattices are vertically aligned. According to the invention, the high-density storage function of optical discs is realized by the rotary optical disc storage device. The above storage device is rotated by an optical disc juke-box, and then a target optical disc can be quickly grabbed. Meanwhile, the data efficiently reading function and the safety protection function can be realized or the backup data of a hard disc module by means of a magneto-optical converged storage device.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a rotary optical disc storage device, an optical disc library and a magneto-optical fusion storage device. Background technique [0002] The optical disc library in the prior art is an array-type cabinet fixedly placed on the ground. In front of the cabinet, there is a manipulator that can move horizontally and vertically. When picking up the disc, the manipulator moves to the target disc under the control of the controller. In front of the magazine, extract the tray in the disc box, and grab and carry the discs in the tray. Due to the uncertainty of disk retrieval, two consecutive target disks may be far apart, and the movement of the manipulator is time-consuming and laborious, resulting in low disk retrieval efficiency and low stability of the traditional optical disk library. [0003] In addition, when the processor reads data, it often calls the data in the hard disk. This is be...

Problems solved by technology

Due to the uncertainty of disk retrieval, two consecutive target disks may be far apart, and the movement of the robot is time-consuming and laborious, resulting in low disk retrieval efficiency and low stability of the traditional optical disk library.

[0003] In addition, when the processor reads data, it often calls the data in the hard disk. This is because compared with the optical disk, the hard disk reads the disk faster. However, the problem of data security is ignored in the prior art. The hard disk is a kind of The data carrier using the current magnetic effect has a certain lifespan, especially after being bumped and worn, it is very likely to cause fatal damage to the hard disk, and once the hard disk is damaged, the data in the hard disk will face irreversible loss, and The hard disk is expensive and not suitable for data backup. In the information age where data security is highly valued, the security of the data system puts forward new and higher requirements for the equipment.
