Burning policy control method and information burning device

Abstract

The invention relates to a recording strategy control method, which comprises the following steps: on-line detection is performed in the process of recording an optical disk; whether an error occurs or the preset check point is achieved is determined; if an error occurs or the preset check point is achieved, the recording is suspended, and off-line detection is performed; whether recorded data error rate exceeds the predetermined value is determined; if the recorded data error rate exceeds the predetermined value, the recording speed is reduced; the recording strategy is adjusted according to the off-line detection result and the reduced recording speed. The recording strategy control method makes detection on the recording quality in the actual recording process, performs adaptive adjustment to the recording strategy according to the detection result, ensures the recording strategy to adapt to the quality and the operating environment of the optical disk, and improves the recording quality. In addition, the invention also provides an information recording device using the recording strategy control method.

Description

technical field [0001] The invention relates to an information recording device, in particular to a recording strategy control method of the information recording device. Background technique [0002] In recent years, information recording media such as recordable optical discs (DVD-R / RW, DVD+R / RW or CD-R / RW) have become more and more popular as carriers for recording information due to their large storage capacity and portability. more and more widely used. An information recording device for recording information to a recording medium is welcomed by users because it can provide users with self-recording information. Corresponding information recording technology has also been developed rapidly. Generally, an information recording device uses an optical pick-up unit (OPU) to emit a laser beam to converge on an information recording medium. When the output laser recording power reaches a given value and is correctly focused on the recording layer of the optical disc, the i...

[0005] However, in the actual recording process, if only a predetermined recording strategy is used without making adaptive changes to the recording strategy during the recording process, it will be affected by the quality of the disc itself and the use environment, such as the thickness of the dye layer in different regions of the disc, the disc The inclination, fingerprints on the disc, etc. will be different, so that the recording quality cannot be kept at its best, and may even cause the recording to fail and the disc to be scrapped
