An automatic reading and writing device for double-sided optical discs

Abstract

The invention relates to the field of data read, and discloses an automatic read-write device for a double-sided disc. The automatic read-write device for the double-sided disc comprises a controller, a disc drawing device, a disc grabbing device, a CD driver and a box bin. The box bin comprises two openings, wherein one opening is used for storing a double-sided disc box, and the disc drawing device is used for drawing a tray of the double-sided disc box from the other opening of the box bin. The disc grabbing device is used for grabbing a disc on the tray and placing the grabbed disc into the CD driver. The actions of the disc drawing device, the disc grabbing device and the CD driver are controlled by the controller. According to the automatic read-write device for the double-sided disc, the disc drawing device can directly draw the tray, the disc grabbing device grabs the double-sided disc on the tray and places the double-sided disc into the CD driver for disc read-write operation, the disc read-write operation is selectively conducted on the front face and the rear face of the double-sided disc, and the read-write efficiency of the double-sided disc is improved.

Description

technical field [0001] The invention relates to the field of data reading, in particular to an automatic reading and writing device for double-sided optical discs. Background technique [0002] In the existing optical disc reading technology, the manipulator moves to the front end of the disc magazine of the optical disc library, uses the disc extractor to extract the tray of the disc case, and then uses the disc grabber to grab the disc and move it to the read-write device, open the optical drive, and grab the disc. Put the disc you took into the tray of the optical drive, and finally close the optical drive to read and write the disc. [0003] Obviously, the existing read-write device has a transportation process for the optical disc. This read-write device is suitable for reading and writing optical discs with a large storage capacity, that is, a single-sided optical disc that can only read and write data on one side, and the data storage capacity is small. , On the othe...

Problems solved by technology

[0003] Obviously, the existing read-write device has a transportation process for the optical disc. This read-write device is suitable for reading and writing optical discs with a large storage capacity, that is, a single-sided optical disc that can only read and write data on one side, and the data storage capacity is small. , the other side causes a waste of resources and space

The double-sided optical disk can read and write information data on both sides to expand the data storage capacity, but the biggest factor limiting the application of the double-sided optical disk is that the double-sided optical disk is easy to scratch the surface of the optical disk during manual operation, resulting in data damage and loss. The disc lock is placed in a closed disc box that cannot be touched by human hands, so the selective reading and writing operation of any side of the double-sided disc becomes a problem that needs to be solved

[0004] A common CD case includes a tray that can hold a CD. The CD is placed on the bottom of the tray. If a double-sided CD is stored in a normal CD case, if the CD needs to be read, if the CD is picked up by a manipulator , pull out the tray from the disc box, and the manipulator grabs the double-sided disc from top to bottom. If you flip the front and back of the ordinary disc and perform the same operation, the manipulator will not be able to grab the double-sided disc, and the double-sided disc will fall out of the tray. Therefore, using traditional ordinary discs to store double-sided discs cannot perform selective double-sided read and write operations on double-sided discs
