Claims (6)
- 스핀들 모터에 의해 회전되고 있는 디스크의 회전 각속도를, 현재 재생되고 있는 디스크의 재생 위치정보에 근거하여 검출함과 아울러, 상기 스핀들 모터의 감속에 따른 디스크 회전 감속 비를 검출하는 1단계;상기 검출된 디스크의 회전 각속도와 디스크 회전 감속 비를 참조하여, 브레이크 전압 인가시간을 산출하는 2단계; 및상기 산출된 시간 동안, 브레이크 전압을 스핀들 모터에 인가하여, 디스크를 정지시키는 3단계를 포함하여 이루어지는 것을 특징으로 하는 광디스크 장치에서의 디스크 정지 제어방법.
- 삭제
- 제 1항에 있어서,상기 디스크 회전 감속 비는, 상기 스핀들 모터를 감속시킨 시점부터 소정 시간 경과 후, 감속된 디스크 회전 속도에 근거하여 검출되는 것을 특징으로 하는 광디스크 장치에서의 디스크 정지 제어방법.
- 제 1항에 있어서,상기 브레이크 전압 인가시간은, 상기 디스크의 회전 각속도와 디스크 회전 감속 비에 비례하는 시간 값으로 산출되는 것을 특징으로 하는 광디스크 장치에서의 디스크 정지 제어방법.
- 제 1항에 있어서,상기 디스크 회전 감속비는, 기 설정된 회전속도로 감속시키기까지 소요되는 시간에 근거하여 산출하는 것을 특징으로 하는 광디스크 장치에서의 디스크 정지 제어방법.
- 제 1항에 있어서,상기 1단계는, 스핀들 모터에 의해 회전되고 있는 디스크 회전 각속도를, 현재 재생되고 있는 디스크의 재생 위치정보에 근거하여 검출하는 단계;상기 디스크의 회전 각속도를 기 설정된 회전속도로 감속시키는 단계;상기 기 설정된 회전속도로 감속시키기까지 소요되는 시간에 근거하여 회전 감속비를 산출하는 단계로 이루어지는 것을 특징으로 하는 광디스크 장치에서의 디스크 정지 제어방법.
