Description

대각선 트랙녹화의 주사에 관한 처리방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 자기밴드상의 대각선 트랙의 배치를 나타낸도.
제2도는 자기밴드에 의한 헤드바퀴(Kopftrommel)의 감김을 나타낸도.
제3도는 자기밴드 상의 대각선 트랙의 연속상을 나타낸도.

Claims (13)

  1. 녹화에 대하여, 기록테이프의 종속도(V)와 헤드속도가 상이한 상태에 있을 때
    a) 헤드와 트랙에 비스듬한 방향을 이루고 있는 테이프 사이에서 상대적인 운동을 생산하기 위한 장치의 추진력 기록테이프의 속도로부터 유도되며:
    b) 헤드-밴드-접선의 길이가 주사하는 시그널트랙의 길이보다 길고,
    c) 시그널 주사를 위해 이용된 밴드-헤드-접촉 범위가 밴드-헤드-접촉선의 내부에서 변화될 수 있는 조처를 특징으로 하는 대각선트랙 녹화 주사에 관한 처리방법.
  2. 제1항에 있어서, 녹화테이프의 종속도(V)를 고정된 헤드로써 측정할 수 있도록 하기 위해 감시트랙 또는 제어트랙이 주사되는 것을 특징으로 하는 처리방법.
  3. 제1항에 있어서, 주사속도(W)가 그의 공칭값을 유지하도록 기록테이프의 종속도(V)에 따라서 헤드속도(U)가 변화되는 것을 특징으로 하는 처리방법.
  4. 제1항 내지 제3항에 있어서, 헤드와 트랙방향에 비스듬히 놓여있는 녹화테이프 상이의 상대운동이 헤드진로가 테이프상의 트랙에 평행하게 진행하도록 조절되는 것을 특징으로 하는 처리방법.
  5. 제4항에 있어서, 제어트랙의 시그널이나 대각선트랙에 포함된 ATF-시그널을 이용하는 표준 개폐장치를 사용함으로써 트랙이 바르게 안내되는 것을 특징으로 하는 처리방법.
  6. 상기항중 어느 한항에 있어서, 그 주위에 서로 90°간격으로 자리를 잡고있는 헤드가 배열된 회전헤드 바퀴를 사용하여 주사되는 것을 특징으로 하는 처리방법.
  7. 제6항에 있어서, 서로 연속하는 헤드가 여러 가지 방위각을 갖는 것을 특징으로 하는 처리방법.
  8. 제6항에 있어서 테이프상의 트랙길이가 90°감기는 동안 테이프는 헤드바퀴에 거의 120°감기는 것을 특징으로 하는 처리방법.
  9. 상기항중 어느한항에 있어서, 헤드전환이 주사된 시그널에 의해 조절되는 것을 특징으로 하는 처리방법.
  10. 상기항중 어느한항에 있어서, 밴드형 녹화테이프의 경우 밴드폭의 절반만 대각선트랙을 수용하며 헤드의 주사운동이 밴드 중심으로부터 밴드 가장자리로 진행하는 것을 특징으로 하는 처리방법(제6도).
  11. 제1항에 있어서, 경우에 따른 종속도(V)의 측정과 추진력상의 이득을 위한 접속이 예측되는 것을 특징으로 하는 처리방법.
  12. 제1항에 있어서, 이미 주어진 종속도(V)에 의해 추진력의 크기가 결정되는 것을 특징으로 하는 처리방법.
  13. 제1항에 있어서, 헤드와 헤드방향에 비스듬한 테이프사이의 상대운동 헤드바퀴의 축방향으로 헤드바퀴를 운반하는 헤드의 변위를 통해 일어나는 것을 특징으로 하는 처리방법.
