Optical disk reading method

Abstract

Disclosed is a method for reading CD which comprises: (a) reading address according to an amplification signal which corresponds to a reading speed; (b) checking whether reading successfully, if it does, then ending this method; if not, then moving to step (c); (c) adjusting the amplification signal corresponded to the reading speed according to a reading error index value; (d) re-reading address according to the adjusted amplification signal; (e) checking whether reading successfully, if not, repeating step (c).

Description

technical field [0001] The present invention relates to a reading method, and in particular relates to a reading method of an optical disc. Background technique [0002] Please refer to figure 1 , which shows a block diagram of a traditional optical read-write control system. The optical read / write control system 100 at least includes an optical pickup head 110 , a radio frequency equalizer (radio frequency equalizer) 120 and a digital signal processing (Digital Signal Processing, hereinafter referred to as DSP) unit 130 . The DSP unit 130 includes a decoder 132 and an error corrector 134 . [0003] When the optical read-write control system 100 reads the data of an address of the optical disc 111 at a reading speed of 52 times, for example, the optical read-write head 110 emits a laser light L to the optical disc 111 and reads the data from the optical disc 111. The reflected radio frequency signal RF 1 is output to the radio frequency equalizer 120 . The radio frequenc...

Problems solved by technology

In this way, the optical read / write control system 100 will still be unable to correctly read the data stored at this address, and will also increase the time required to read this address
