A disk drawer and optical disc library used in optical disc library

Abstract

The invention discloses a disc drawer used in an optical disc library, which comprises a casing and a linked first claw and a second claw arranged on the casing, and the claws of the two claws located on one side of the casing are The hooks form a set of drawer claws, and the two claw hooks on the other side of the housing form another set of drawer claws. When one set of drawer claws closes inward, the other set of drawer claws opens outward. The invention also discloses an optical disc library. When the disc tray in the disc case is completely drawn out by one set of drawer claws of the disc drawer, another set of drawer claws can enter the unlocking hole of the disc case facing the set of drawer claws. The invention only needs two claws to unlock the disc boxes on both sides, and has a simple structure. The present invention creatively uses the space in the disc box to accommodate the jaws of the disc drawer, thereby more effectively utilizing the space in the disc library, and skillfully solves the problem that the space of the disc library is too narrow to accommodate the double-sided drawer.

Description

technical field [0001] The invention relates to an optical disc library, in particular to a disk drawer used in the optical disc library. 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. [0003] An optical disc library generally includes a disc magazine, an optical drive, a manipulator assembly and a control unit, and the manipulator assembly further includes a disk drawer, a disk grabber, and a displacement device that drives the disk dra...

AI Technical Summary

Problems solved by technology

Take the 19-inch standard cabinet as an example, the width of the cabinet is 482.6mm, and the distance between the two sets of disc magazines placed oppositely in the cabinet is not greater than 153.5mm, and when the disc tray on one side of the disc magazine is completely pulled out, its The distance to the disc magazine on the other side is only 28.5mm, that is to say, the size of the drawer should be limited to less than 3 cm in space, while the existing drawer can unlock the disc magazine on one side At the same time, the claws on both sides must be closed at the same time. This design makes it impossible to use the space of the disc cartridge. The two pairs of claws must occupy the space between the disc cartridges, and because the electromagnet is required to drive the connecting rod to drive the pair of claws to move , the pair of claws engages with the other pair of claws in the unlocking direction. Such a complex structure makes it difficult to make it small in the unlocking direction and cannot be accommodated in a small space.
