제1도는 본 발명에 의한 디스크 장치의 일실시예를 도시하는 개략계통도,
제2도는 제1도의 트래버스 검출회로(5)의 상세한 구성을 도시하는 블록도,
제3도는 고속용 트래버스 검출회로의 동작 설명에 제공하는 신호 파형도.

Claims (1)

  1. 헤드수단이 디시크위의 기록 트랙을 트래버스할 때에, 상기 헤드수단의 출력신호에 의거하여 트래버스 검출 펄스신를 형성하여, 이 트래버스 검출 펄스신호의 펄스수를 카운트하므로서 트래버스 트랙수를 검출하도록 된 디스크 장치에 있어서, 상기 헤드수단의 출력 신호에 포함되는 데이터 신호 성분에 의거하여 트리거되는 타이머 회로를 가지고, 상기 타이머 회로의 설정시간을, 상기 데이터 신호 성분의 주기 가운데 가장 긴 주기 보다 약간 긴 값으로 설정하여, 상기 타이머 회로의 출력을 상기 트래버스 검출 펄스신호로서 얻어지는 것을 특징으로 하는 디스크 장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
