Claims (1)

  1. 디지탈신호를 시간축에 압축하여 복수개의 회전헤드에 의해 경사진 트랙을 가아드밴드를 형성하지 않은상태에서 기록매체상에 형성시켜 기록하고, 이것을 재생하는 장치에 있어서, 상기 각 트랙의 장방형 방향으로 상기 디지탈 신호와는 독립적인 기록영역에서 트래킹용 파일럿 신호를 복수개 기록함과 동시에 인접트랙에서 주파수가 다르며 또한 같은 주파수에 대해서 트랙간에서 기록의 길이가 다른 복수개의 위치표시 신호를 소정수의 트랙마다 되풀이 기록하고, 재생시, 주사폭이 상기 트랙의 폭보다 넓은 회전헤드에 의해 상기 기록트랙을 주사할때에, 상기 위치표시신호의 시단을 기준으로 하여 펄스신호를 형성하고, 이 펄스 신호의 기간중 상기 회전헤드가 주사중인 관련된 트랙에서 상기 파일럿 신호를 검출하고, 이 검출 출력에의해 상기 회전헤드의 트래킹 제어를 행하도록 한 것을 특징으로 하는 디지탈 신호의 기록 재생장치.
