CD read-write equipment and method for manufacturing and regulating/controlling the optical head of the same

Abstract

The invention discloses a compact disc (CD) read-write device for reading and writing a CD through an optical head read-write window of a single-sided disc-protecting box, and a method for regulating and controlling the manufacture of the optical head of the CD read-write device. The CD read-write device comprises general components and structures of the prior CD read-write device such as a CD bracket, an optical head read-write slot of the CD bracket, the optical head, an electric rotating motor head and the like; besides, after the single-sided disc-protecting box sleeved with a CD is put on the CD bracket and put into a chamber and when the optical head reads the CD, the optical head (2) is positioned on the back side of the single-sided disc-protecting box (6) to read and write the CD (9), and the focusing distance of a condensing lens (7) of the optical head is larger than the distance from the back side of the single-sided disc-protecting box (6) to a transmission surface (10) of the CD; or the CD bracket (1) of the CD read-write device is provided with an optical head read-write opening (12), the optical head (2) is positioned on the back side of the optical head read-write opening (12) of the CD bracket to read and write the CD (9), and the focusing distance of the condensing lens (7) of the optical head is larger than the distance from the back side of the CD bracket (1) to the transmission surface (10) of the CD.

Description

technical field [0001] The invention relates to an optical disc reading and writing device composed of an optical disc bracket, an optical head and a rotating motor head, in particular to the optical head structure of the optical disc reading and writing device. In addition, it also relates to a manufacturing control method for the optical head of the optical disc reading and writing device. Background technique [0002] At present, optical discs are the most important means of modern information storage and circulation for human beings. However, due to the direct use of bare optical discs, when the optical discs are repeatedly taken out or put in from the optical disc box and optical disc reading and writing equipment, they will soon be worn and scratched. kind of necessity. [0003] Optical discs generally use one side to store data, and only add a single-sided disc protection box to the light-transmitting surface of the disc that is most likely to be worn and scratched. ...

Problems solved by technology

And when the discs with the single-sided disc protection case are placed together in the disc tray for use, the single-sided disc protection case will close the read-write slot of the optical head of the disc tray, so the traditional read-write equipment for reading bare discs The optical head structure will hit the single-sided disc guard box and cannot work normally, or even damage the optical head. At the same time, it will also prevent the rotating motor head from passing through the rotating motor head hole of the optical disc tray to lift and rotate the optical disc. Therefore, the traditional reading of bare optical discs The optical head structure of the optical disc reading and writing equipment can not be directly used to read and write optical discs with a single-sided disc protection box with an optical head reading and writing window.

[0005] Although I also predicted in the multiple patent schemes I have applied for that I can use the optical head structure of the optical disc read-write device for reading exposed optical discs to read and write optical discs through the optical head read-write window of the single-sided disc guard box, but none Concretely design a practical implementable plan
