Problems solved by technology

Therefore, the heating period Tmn that can produce good writing quality for odd recording marks may not necessarily be used to produce good writing quality for even recording marks, and similarly, the heating period Tmn that can produce good writing quality for even recording marks may not necessarily It can be used to make odd recording marks produce good writing quality. Therefore, if the rewritable optical disk drive 10 burns data according to the known 2T writing strategy, it is not easy to make both odd recording marks and even recording marks correspond to good recording at the same time. quality

Embodiment Construction

[0029] see Figure 4 , Figure 4 It is an operation flowchart of the method for adjusting the 2T writing strategy of the present invention. The method for adjusting the 2T writing strategy of the present invention comprises the following steps:

[0030] Step 100: start;

[0031] Step 102: Write a plurality of odd recording marks and a plurality of even recording marks on an optical disc according to a 2T writing strategy;

[0032] Step 104: Read the plurality of odd recording marks and the plurality of even recording marks to detect corresponding signal intensity distribution characteristics;

[0033] Step 106: Does the timing at which an even recording mark produces the maximum signal strength deviate from an ideal timing? If so, then execute step 108, otherwise, execute step 110;

[0034] Step 108: Using at least two different durations to adjust the 2T writing strategy to reduce the offset between the timing of maximum signal strength and the ideal timing;

[0035] St...

Abstract

The invention refers to a method, optical disk machine and the correcting system for adjusting the 2T writing tactics. The method includes: the optical disk machine is driven to form a test odd record label and a test even record label on a disc, detects the signal waveform corresponding to the two labels, several writing time periods of the even record label are generated according to the signal waveform amendment of the test even record label, several time periods amended according to the test odd waveform label but not according to the even record, in order to generate several time periods for generating an odd record label.

Description

technical field [0001] The present invention relates to an optical disc burner, a method for setting its writing strategy and a calibration system, in particular to a method capable of adjusting a 2T writing strategy to produce the best recording quality, a re-readable optical disc drive and Calibration system. Background technique [0002] In recent years, with the increasingly powerful computing power of computers and the continuous improvement of network technology, users' demand for data storage has greatly increased, so various storage tools have also become popular products, such as The use of optical discs as storage media has always been attracting attention because the unit price of optical discs is low under the same storage capacity, and the volume is light and thin, does not take up space, and is easy to carry. Especially in recent years, various optical disc burners have become increasingly powerful. Reading quality and storage speed have been continuously impr...
