Claims (8)
- 기록 매체에 정보를 기록하거나 기록 매체로부터 정보를 재생할 때 상기 기록 매체에 기록된 회전 제어 정보를 사용하여 상기 기록 매체의 회전을 제어하는 기록/재생 장치에 있어서,상기 회전 제어 정보로부터 상기 기록 매체를 회전시키기 위한 에러 전압을 발생시키는 발생 수단과,상기 에러 전압에 포함된 잡음으로 인한 극성 변동이 제거된 후에 상기 에러 전압의 극성을 판정하는 판정 수단과,상기 에러 전압의 크기를 검출하는 검출 수단과,상기 판정된 에러 전압의 극성과 상기 검출된 에러 전압의 크기에 따라 상기 기록 매체를 회전시키는 회전 수단을 구비하는, 기록/재생 장치.
- 제 1 항에 있어서, 상기 판정 수단은 저역 필터를 사용하여 상기 에러 전압의 상기 잡음에 의한 변동을 제거하는, 기록/재생 장치.
- 제 1 항에 있어서, 상기 판정 수단은 상기 에러 전압과 미리 정해진 기준 전압의 크기를 비교하고, 상기 비교 결과의 미리 정해진 시간의 지연을 갖는 신호와 상기 비교 결과의 지연을 갖지 않는 신호의 차이에 기초하여 상기 잡음에 의한 변동 성분을 제거하는, 기록/재생 장치.
- 제 1 항에 있어서, 상기 판정 수단은 상기 동작이 기록 또는 재생되는지에 따라 제거될 변동 주파수를 변화시키는, 기록/재생 장치.
- 제 1 항에 있어서, 상기 판정 수단은 상기 기록 매체의 종류에 따라 제거될 변동 주파수를 변화시키는, 기록/재생 장치.
- 제 1 항에 있어서, 상기 회전 수단으로 스핀들 모터가 제공되는, 기록/재생 장치.
- 제 6 항에 있어서, 상기 기록/재생 장치에 상기 스핀들 모터의 회전을 감속하는 감속 수단이 부가적으로 제공되는, 기록/재생 장치.
- 기록 매체에 정보를 기록하거나 기록 매체로부터 정보를 재생할 때 상기 기록 매체에 기록된 회전 제어 정보를 사용하여 상기 기록 매체의 회전을 제어하는 기록 매체 회전 제어 방법에 있어서,상기 회전 제어 정보로부터 상기 기록 매체를 회전시키기 위한 에러 전압을 발생시키는 단계와,상기 에러 전압에 포함된 잡음으로 인한 극성 변동이 제거된 후에 상기 에러 전압의 극성을 판정하는 단계와,상기 에러 전압의 크기를 검출하는 단계와,상기 판정된 에러 전압의 극성과 상기 검출된 에러 전압의 크기에 따라 상기 기록 매체를 회전시키는 단계를 구비하는, 기록 매체 회전 제어 방법.
