Description

영상신호와 음성신호의 재생장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제5도는 본원 발명의 재생장치의 일예를 나타낸 접속도.
제6도는 그 설명을 위한 특성곡선도.
제7도∼제9도는 테이프 기록방식을 기계적으로 검출하는 경우의 일예를 나타낸 카세트의 평면도 내지 재생장치의 검출기구의 측면도.

Claims (1)

  1. 테이프의 주행방향에 대해서 경사진 영상트랙에, 주파수 변조된 휘도신호와 저역 변환된 반송색신호로 이루어진 영상신호가 기록되고, 음성신호가 기록되지 않으며, 테이프의 주행방향으로 연장되는 음성트랙에 음성신호가 기록된 제1의 자기테이프와, 테이프의 주행방향에 대해서 경사진 영상트랙에 주파수 변조된 휘도신호와 저역 변환된 반송색신호로 이루어진 영상신호와 이들 주파수 변조된 휘도신호와 저역변환된 반송색신호간의 대역을 차지하는 주파수 변조된 음성신호의 혼합신호가 기록된 제2의 자기테이프의 각각 상기 영상트랙에 기록된 신호를 재생하는 회전자기헤드와, 이 회전자기헤드의 재생출력으로부터 상기 주파수 변조된 음성신호의 대역의 신호성분을 제거하는 대역제거필터와, 상기 회전자기 헤드의 재생출력에서 상기 제1 또는 제2의 자기 테이프의 상기 영상트랙에 기록된 영상신호를 재생하는 영상신호재생계와, 고정자기헤드)에 의해 상기 제1의 자기테이프의 상기 음성트랙에 기록된 음성신호를 재생하는 제1의 음성신호재생계와, 상기 회ㅈ너자기헤드의 재생출력으로부터 상기 주파수 변조된 음성신호를 분리해서 복조하는 제2의 음성신호재생계와, 재생되는 자기테이프가 상기 제1의 자기테이프인지 상기 제2의 자기테이프인지를 검출하는 검출수단을 가지며.이 검출수단의 검출 출력에 의해. 재생되는 자기테이프가 상기 제1의 자기테이프일때는 상기 제1의 음성신호 재생계에서 얻어지는 음성신호가 음성신호 출력단자에도출되는 동시에. 상기 회전 자기헤드의 재생 출력이 상기 대역 제거 필터를 통함이 없이 상기 영상신호재생계에 주어지도록 절환되며. 재생되는 자기테이프가 상기 제2의 자기테이프 일때는 상기 제2의 음성시호 재생계에서 얻어지는 음성신호가 상기 음성신호 출력단자에 도출되는 동시에, 상기 회전 자기헤드의재생 출력이 상기 대역 제거 필터를 통해서 상기 영상신호 재생계에 주어지도록 절환되는 영상신호와 음성신호의 재생장치.
