AI Technical Summary

Problems solved by technology

In this case, these components tend to fall into excessively high operating temperatures, which makes the entire housing of the read / write head 15 prone to heat and cause errors in the read / write program
In particular, when the optical read-write head 14 is performing the burning operation, since a higher-power laser beam is used to burn data on the recording layer on the optical disc, the heat dissipation problem of the entire read-write head 15, will become more serious

Embodiment Construction

[0015] The present invention provides a heat sink installed on the upper side of the read / write head of an optical disc drive. By making an upwardly raised or raised surface structure on the heat sink, the wind-impacting area of ​​the heat sink is increased, and further Improve its cooling efficiency. A detailed description of the present invention is as follows.

[0016] Please refer to figure 2 , this figure shows the read / write head 20 provided by the present invention. The read-write head 20 is assembled in the optical disk drive, and the sliding sleeve 201 on the side of the read-write head 20 is inserted on the slide rail 30 in the optical disk drive, so that the read-write head 20 can move along the slide rail Move back and forth. The read-write head 20 includes a base (carriage) 200, an optical element (not shown), a laser diode (not shown), a voice coil motor 202, a control chip 203, a reinforcing board 204 and a flexible circuit board (FPC) 205. Wherein, the ba...

Abstract

A kind of read-write head that with the heat-dissipating apparatus. The heat-dissipating apparatus comprises one cooling plate that installed on the upper surface of the read-write head, which is on the inside of the CD driver. There is formed the raised superficial structure that on the upper surface of the cooling plate. The structure can expand the air-contact area of the cooling plate and increase the heat-dissipating efficiency.

Description

(1) Technical field [0001] The invention relates to a pick-up head in an optical disc drive, in particular to a pick-up head with a cooling plate to greatly improve the heat dissipation efficiency of the pick-up head. (2) Background technology [0002] With the rapid development of personal computers, computer peripheral products are also growing rapidly and changing with each passing day. Computer peripheral products such as hard disk drives, optical disc drives, scanners, printers, etc. have become necessary tools for modern offices, and with the reduction of product prices, computer peripheral products have also been popularized from offices to families. Among them, the optical disc drive is a very convenient and widely used storage medium at present, not only because the optical disc has a huge storage capacity, but also because the stored data can include music and image formats, and can be preserved for a long time. Especially, with the development of a new generation...
