Claims (1)

  1. 영상신호를 기록용의 영상신호로 변환하는 것과 함께 아날로그의 음성신호를 일정한 주파수로 샘플링 하여 디지털 음성 신호로 하고, 이 기록용의 영상신호와 디지털 음성신호를 자기테이프의 긴 방향으로 경사진 트랙에, 장승층의 깊이 방향이 다른 부분으로 나누어서, 또는 시분할하여, 또는 별도의 트랙으로 하여 기록하고, 이 자기테이프로부터 기록용이 영상신호를 재생하여 영상신호로 하는 것과 함께 디지털 음성 신호를 재생하여 음성 신호로 하는 자기기록 재생방식에 있어서, 이 영상신호의 1필드 또는 1 플레임 기간내의 음성신호의 샘플수의 이 영상 신호의 필드 주파수에 의한 1/5 또는 1/6n(n은 자연수)의 수정치에 비해, 큰 샘플수의 제 1 의 블럭과 적은 샘플수의 제 2 의 블록을 이 필드 주파수에 의한 순서를 사용해서 이 1 필드 또는 1플레임 기간내의 음성 신호의 전 샘플을 차례로, 각각의 블록에서 완결하도록 부호화를 행하고, 또한 1 제의 블록과 제 2 의 블록을 식별하는 식별신호를 부가하여 디지털 음성신호를 생성하여 이 트랙에 기록하고, 재생된 디지탈 음성신호의 각 블럭을 블럭마다 이 식별신호를 참조하여 이 1 필드 또는 1 플레임 기간마다의 전 샘플을 얻고, 얻어진 전 샘플로부터 아날로그의 음성신호를 생성하는 것을 특징으로 하는 자기기록 재생방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
