Description
Claims (1)
- 타 모드에서 플레이모드로 전환하는 제1단계와, 플레이모드에서 플레이모드에 대응하는 드럼모터의 제어전압(VDMC)을 출력하여 드럼의 회전속도와 위상을 제어하면서 드럼의 위상에러를 검출하고, 플레이모드에 대응하는 캡스턴모터의 제어전압(VDMC)을 출력하여 캡스턴의 회전속도와 위상을 제어하면서 캡스턴의 위상에러를 검출하는 제2단계와, 상기 드럼의 위상에러가 기 설정된 허용치(α)이내이고, 상기 캡스턴의 위상에러가 기 설정된 허용치(β)이나 인지를 판단하는 제3단계와, 상기 제3단계의 판단 결과 허용치(α),(β) 이내가 아니면 제3단계를 반복수행하고, 허용치(α),(β) 이내이면 오토트랙킹 동작을 수행하는 제4단계로 이루어지는 것을 특징으로 하는 브이씨알의 위상오차 검출에 의한 오토트랙킹 방법.
