Claims (7)

  1. 자기테이프(B)에 의해 부분적으로 감기는 비디오 헤드(K1, K2)를 가진 회전하는 헤드드럼(KT), 헤드드럼(KT)상에 있는 최소한 하나의 펄스발생기(M), 하나의 비디오 헤드에서 다른 비디오헤드로 전환시키는 헤드전환 신호를 발생시키기 위한 최소한 하나의 센서(S)와 재생시 수직동기신호를 주사하기 위한 컨트롤헤드(KK)를 가진 비디오 레코더에 있어서, 재생작동시 센서(S)에서 나온 신호와 수직동기신호 사이의 시간이 측정되어 목표값과 비교되고, 이 비교에서 헤드전환신호의 시간적 위치를 조절하기위한 기준이 얻어지는 것을 특징으로 하는 비디오 렉코더.
  2. 제1항에 있어서, 상기 비교에서 얻어진 기준이 테이프 속도를 조절하기위해 사용됨으로써 헤드전환신호의 시간적 위치가 조절되는 것을 특징으로 하는 비디오 레코더.
  3. 제1항에 있어서, 비교에서 얻어진 기준이 수직동기 신호전 센서(S)의 신호에 따라 조절가능한 시간에 헤드전환신호를 발생시키는데 사용되도록 헤드전환신호의 시간적위치가 조절되는 것을 특징으로 하는 비디오 레코더.
  4. 제3항에 있어서, 센서(S)에서 나온 신호의 시간적 위치는 자기테이프에서 표준에 따른 기록을 재생할 때 헤드전환신호가 센서(S)에서 나온 신호와 수직동기신호 사이의 시간간격중앙에 놓이도록 선택되는 것을 특징으로 하는 비디오 레코더.
  5. 제3항 또는 4항에 있어서, 센서(S)에서 발생된 신호는 펄스형태이며 카운터(Z)의 리세트입력에 공급되고, 카운터(Z)의 스톱입력에는 펄스형수직동기신호가 공급되며, 카운터(Z)의 출력은 비교기(VL)의 제1입력에 접속되고, 비교기(VL)의 제2입력은 목표값 송신기(D)의 출력에 접속되고, 비교기(VL)의 출력은 제어 가능한 지연회로(VZ)의 제어입력에 접속되고, 지연회로(VZ)의 출력에서는 펄스형 헤드전환신호가 얻어지고, 클럭발생기(G)의 출력은 카운터(Z), 목표값송신기(D) 및 제어가능한 지연회로(VZ)의 클럭입력에 접속되는 것을 특징으로 하는 비디오 레코더.
  6. 제5항에 있어서, 수직동기신호의 짧은 드롭 아웃시에 신호 탈락 전 펄스형 헤드전환신호의 시간적위치가 유지되는 것을 특징으로 하는 비디오 레코더.
  7. 제6항에 있어서, 수직동기신호의 계속적인 드롭 아웃시펄스형 헤드전환신호가 기록작동시와 동일한 시점에서 발행되는 것을 특징으로 하는 비디오 레코더.
