Claims (4)
- 에어갭이 상호 평행으로 안내되는 자기 트랙에 있어서 교대로 변화하는 애지머스 각도를 갖고 있는 회전하는 자기 헤드를 사용하여 유효 신호를 기록 및 재생하는 자기 테이프 장치로서, 써보계에 의한 트랙 추종 제어(트랙킹)이 행해지고, 그때 써보계의 제어는 기록된 제어 신호의 동시 기록의 평가에 의해 행해지는 것에 있어서, 제어신호는 유효 신호에 대하여 부가적으로 자기 트랙의 트랙 부분에 있어서 버스트로서 기록되어 있는 즉 각각 3개의 트랙군에 있어서 상기 트랙부분의 중간 트랙이 제어신호없이 또 각각 3개의 트랙의 2개의 군 사이에서 있어서 상기 트랙 부분에 있어서 하나 또는 복수의 트랙이 제어 신호없이 배치된 것을 특징으로 하는 자기 테이프 장치.
- 제어 신호의 주파수가 일정하고 또 제어신호를 갖는 트랙부분은 트랙 시장단에서 보아 서로 교대로 변경하여 배치되어 있는 1항의 기재에 따른 자기 테이프 장치.
- 제어 신호를 갖는 트랙 부분은 포랙 시작단에 대하여 같은 거리를 갖고 또한 제어 신호는 상기 트랙부분에 있어서 교대로 2가지 다른 주파수를 갖는 제1항의 기재에 따른 자기 테이프 장치.
- 제어 신호의 주파수는 재생 작동에 있어서 트랙의 독취시, 인접하는 트랙의 동시 기록은 자기 헤드의 에어갭의 애지머스의 간격에 의해 방해되지 않는 정도의 저주파인 제1항에 기재에 따른 자기 테이프 장치.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
