Balancing set for optical disk in optical disk driver

Abstract

The invention relates to a CD balancing device for a CD-ROM, comprising the parts: a loading substrate; a CD guiding part on the substrate; roller on the upper part of the CD guiding part; elastic tool, providing specific bounce for keeping CD balanced between the CD guiding part and the roller and able to reduce the space between them. The invention can prevent the moving CD from rotating so as to achieve the effect of reducing noises caused by the space.

Description

(1) Technical field [0001] The present invention relates to an optical disc drive, in particular to a disc balancing device for an optical disc drive that can automatically maintain disc balancing when a disc is inserted. (2) Background technology [0002] In general, methods for transferring an optical disk in an optical disk drive can be classified into a tray method, a finger method, and a roller method. Among them, the tray method refers to the method of placing the disc on the tray formed on the contact surface of the disc to move and transfer the disc; the finger method refers to the method of holding the edge of the disc with fingers to transfer the disc; the roller method is used as a roller. When it is in close contact with the surface of the disc, the friction between the two is used to transfer the disc. [0003] The optical disk drive of the above-mentioned roller transfer method is composed of the following parts: a roller driving part that transfers the optica...

Problems solved by technology

[0007] However, if figure 2 As shown, when the optical disc 10 is inserted, due to the difference in balance, there may be problems in the transfer path and loading action of the optical disc 10

[0008] In other words, since the left / right side of the roller outer diameter (R1) is not fixed, that is, when the rubber material roller 30 is used for a long time, since wear can occur, a difference occurs in the left / right side outer diameter, and disc transfer is not smooth. able to accurately

[0009] Moreover, since the heights of the left / right sides (H1, H2) of the disc guide 20 provided on the loading substrate 40 also differ in height

That is, even if the difference in height between the left and right sides of the disc guide 20 is only about 0.1mm, there is a problem that the disc is rotated and inserted or the insertion force is lowered during loading.
