Embodiment Construction

[0018] In order to fully understand the present invention, the legends related to the present embodiment will be specifically described.

[0019] figure 1 is a simplified block diagram of an optical disc drive incorporating the data recording method employed by the present invention.

[0020] figure 1 The optical disc drive includes: a digital recording signal processing unit 30a, which is used to convert the input data into EFM (eight to fifteen modulation) data in the form of recording, and add additional error correction code (ECC) at the same time; a channel bit encoding A device 40 is used to convert the data in the recording form into a write signal; an optical drive 41 is used to generate a signal to drive an LD (laser diode); an optical sensor 20 is used to write a signal on the surface of the writable optical disc 10, Or read the written signal from the surface of the writable optical disc 10; an R / F mechanism, which can generate binary signals and TE (tracking erro...

Abstract

The present invention relates to a method for recording recording data into an optical disc drive using a writing strategy which is related to the recording characteristics of the optical disc. The method of the present invention is to detect the track pitch or storage capacity of the recording medium, and adjust the write strategy according to the detected track pitch or storage capacity. At this time, the write strategy will be consistent with the medium manufacturer, and the adjusted write strategy will be The input data is recorded to the recording medium. Therefore, the quality of reproduced data will be improved in the future, and even the recording ability to non-standard optical discs is also improved compared to standard ones.

Description

technical field [0001] The invention relates to a method for recording data in an optical drive, which uses an optical drive writing strategy consistent with the recording characteristics of the optical disc. Background technique [0002] Generally, the characteristics of writable optical discs are different, and the difference in characteristics is attributed to their different manufacturing companies. [0003] Therefore, an optical disc device, such as a CD writer, incorporates an Optimal Power Corrector (OPC) to use the standard write power given by the disc manufacturer in order to obtain the optimum write power. [0004] In addition, each writable optical disc manufacturing company is different, and the writing strategy for writable optical discs is also different. Therefore, a microprocessor of an optical disc device stores information of a special writing strategy associated with each company's standard storage capacity (eg, 74 seconds) of the optical disc, and dete...
