Description

광 디스크장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 한 실시예에 의한 광자기 디스크 장치의 전체구성을 도시한 블럭도면. 제2도는 복조된 바이패이즈 마크신호를 도시한 신호파형 도면. 제3도는 스핀들 제어회로의 구성을 도시한 블럭도면.

Claims (1)

  1. 소정의 데이타 신호가 주파수 변조되어서 이뤄어지는 워플 신호에 의해서 프리 그룹이 형성된 광디스크를 선속도 일정으로 구동하도록 된 광 디스크 장치에 있어서, 재생된 상기 워플 신호를 소정의 기준신호와 비교해서 상기 광 디스크를 회전하는 스핀들 모우터를 거의 선속도 일정으로 구동 제어하는 제1의 스핀들 서보수단과, 상기 워플 신호를 복조해서 얻어지는 상기 데이타 신호가 정확하게 꺼내졌는지 아닌지에 따라서, 상기 제1및 제2의 스핀들 서보수단을 절환 제어하는 절환 수단을 구비하는 것을 특징으로 하는 광 디스크장치.
