Abstract

The dynamic determination method of etching speed of optical disk etching machine includes the following steps: presetting at least an error admissible upper limit in every presetting time, calcualting a data error rate when the optical disk etching amchine is operated in a presetting time at a correspondent etching speed and comparing error admissible upper limit with data error rate, when the data error rate is less than error admissible upper limit, said etching speed can be switched to higher etching speed, if the data error rate is greater than the admissible upper limit, said optical disk etching machine can be continuously operated at said speed.

Description

technical field

[0001] The invention provides a method for dynamically determining the recording speed of an optical disc recorder, especially a method for dynamically adjusting the recording speed according to the data error rate of the recording object. Background technique

[0002] At present, the recording speed of CD-R recorders on the market has reached 24 times, and the continuous improvement of recording speed is a foreseeable development trend. However, the characteristics of optical discs produced by different optical disc manufacturers are not exactly the same, and the data recording conditions at the same recording speed are also different. At a certain data recording speed, it may happen that a certain brand of discs can completely and correctly perform data recording, while another brand of discs may have data recording loss, or the recording is complete but cannot be read. Take unexpected situations.

[0003] When the optical disk is manufactured and leaves ...
