Claims (1)

  1. 비디오 테이프 레코더의 트래킹 제어방법에 있어서, 초기 트래킹 데이터를 출력한 다음 1헤드스위칭 펄스 발생 주기동안 오디오와 비디오 앤벌로프 신호를 소정횟수 샘플링하여 적산하고 앤벌로프신호 대소를 검출하여 트래킹 데이타를 변경하는 트래킹 제어 과정과, 상기 트래킹 제어과정 실시후 앤벌로프 파형 총화치 피크점을 최적점으로 설정하여 최적 트래킹데이터를 출력하는 최적점 검출 과정과, 상기 최적점 검출후 제어펄스를 검출하여 연속하여 일정 횟수 이상 검출되지 않거나 검출되더라도 오디오/비디오 앤벌로프가 최소치 이상이거나 오디오/비디오 앤벌로프는 최소치 이하이더라도 테이프속도가 변경될시 재생모드가 해제되지 않았으면 상기 트래킹 제어과정을 재실시토록 제어하는 감시 과정으로 이루어짐을특징으로 하는 최적위치 트래킹 자동 제어방법.
