Claims (1)
- 정상 재생 모드시에 있어서, 회전헤드를 회전시키는 드럼모터의 회전 검출신호와 일정 주파수의 기준신호를 위상 비교하여 얻은 오차신호를 드럼 모터에 공급하고 드럼모터의 회전위상을 기준신호에 동기케 함과 동시에 재생된 제어펄스와 기준신호를 위상비교하여 자기테이프의 주행을 행하는 캡스턴 모터의 회전위상을 기준 신호에 동기시키는 자기 재생장치의 서보회로에 있어서, 고속 재생 모드시에 드럼모터에의 오차신호의 공급을 정지함과 동시에 기준신호를 회전 검출신호에 위상 동기시키고 캡스턴모터의 회전위상을 회전 검출신호에 동기한 기준신호에 동기하도록 구성하여서 이루어진 것을 특징으로 하는 자기 재생장치의 서보회로.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
