Claims (5)
- 광디스크 재생장치의 초기화 방법에 있어서,상기 광디스크의 소정개의 트랙을 슬레드가 횡단하는데 소요되는 시간을 검출하는 단계;상기 검출된 시간으로부터 상기 슬레드의 1 트랙이동시간을 산출하는 단계;산출된 상기 1트랙 이동시간과 기준 1트랙 이동시간을 비교하는 단계;상기 비교단계를 수행한 결과에 따라, 상기 슬레드의 모터에 인가되는 전압을 제어하는 단계를 포함하여,데크 편차에 상관없이 일정한 슬레드 이동시간을 유지하도록 함을 특징으로 하는 데크 편차에 따른 슬레드 이동시간 조절방법.
- 제1항에 있어서, 상기 전압제어단계는 상기 산출된 1트랙 이동시간이 상기 기준 1트랙 이동시간보다 빠르면 상기 슬레드의 모터에 인가되는 전압을 낮추도록 제어하고, 상기 산출된 1트랙 이동시간이 상기 기준 1트랙 이동시간보다 빠르지 않으면 상기 슬레드의 모터에 인가되는 전압을 높이도록 제어함을 특징으로 하는 데크 편차에 따른 슬레드 이동시간 조절방법.
- 제1항에 있어서, 상기 슬레드가 횡단하는 광디스크의 소정개의 트랙은 전체트랙의 1/4 이상의 트랙 수에 해당되는 것을 특징으로 하는 데크 편차에 따른 슬레드 이동시간 조절방법.
- 제1항에 있어서, 상기 슬레드의 1트랙 이동시간 산출단계는 상기 소정개의 트랙에 대한 상기 슬레드의 이동시간을 상기 슬레드가 이동시 출력되는 미러 수로 나누어 상기 1트랙 이동시간을 산출하는 것을 특징으로 하는 데크 편차에 따른 슬레드 이동시간 조절방법.
- 제1항에 있어서, 상기 슬레드의 1트랙 이동시간 산출단계는 상기 소정개의 트랙에 대한 상기 슬레드의 이동시간을 상기 슬레드가 이동시 출력되는 트랙 수로 나누어 상기 1트랙 이동시간을 산출하는 것을 특징으로 하는 데크 편차에 따른 슬레드 이동시간 조절방법.
