Description
Claims (4)
- 광디스크의 기록파워를 제어하는 방법에 있어서,상기 광디스크의 서로 다른 소정의 영역들 각각에 테스트 데이터를 기록하는 단계와,상기 소정의 영역들 각각에 기록된 테스트 데이터를 재생하고 재생신호들의 베타값들을 검출하는 단계와,상기 베타값들을 비교하고 그 차값을 소정의 기준값과 비교하여 그 결과에 따라 기록 중 재생파워 모니터링을 수반하는 광빔의 파워제어를 선택적으로 실시하는 단계를 포함하는 것을 특징으로 하는 광디스크 기록제어 방법.
- 제 1 항에 있어서,상기 베타값의 차가 4% 이내인 경우에 상기 기록 중 재생파워 모니터링을 수반하는 광빔의 파워제어를 생략하는 것을 특징으로 하는 광디스크 기록제어 방법.
- 제 1 항 또는 제 2 항에 있어서,상기 소정 영역은 상기 광디스크의 기록영역 이외의 영역인 것을 특징으로 하는 광디스크 기록제어 방법.
- 제 3 항에 있어서,상기 소정영역은 상기 광디스크의 최내주영역과 최외주영역을 포함하는 것을 특징으로 하는 광디스크 기록제어 방법.
