Abstract

본 발명은 광자기 디스크의 기록감도(writing sensitivity) 및 CNR 향상방법에 관한 것으로, 더욱 구체적으로는 광디스크에 데이타등의 정보를 기록하는 경우 기록시 디스크의 회전수를 재생시의 경우보다 감소시키고 기록펄스(writing pulse)지속시간은 증가시킴에 따라 디스크의 기록레이저 파우어가 감소되어 광자기 디스크의 기록감도 및 CNR을 향상시킬 수 있도록 한 것에 관한 것이다.The present invention relates to a method for improving the writing sensitivity and CNR of a magneto-optical disc. More specifically, when recording information such as data on an optical disc, the number of rotations of the disc is reduced during recording and the recording pulse is reduced. (writing pulse) duration is related to increasing the recording sensitivity and CNR of the magneto-optical disk by decreasing the recording laser power of the disk as the duration increases.
