Abstract

비디오 테이프 레코더의 4헤드드럼 한개에 의하여 2개의 테이프에 기록, 재생이 가능한 스위칭회로가 기술되는 바, 이 회로는 헤드드럼에 들어온 기록, 재생의 두신호를 처리함에 있어서 1사이클 4분주데이타 출력회로와, 기록, 재생 자동선택회로와, 헤드신호 스위칭 콘트롤 회로와, 헤드신호 스위칭 회로와 헤드신호 라인별 분리회로를 상호 연결구성하여 된 것이다.A single four-head drum of a video tape recorder describes a switching circuit capable of recording and reproducing two tapes. This circuit is a one-cycle, four-division data output circuit for processing two signals of recording and replay entered into the head drum. And a recording, reproducing automatic selection circuit, a head signal switching control circuit, a head signal switching circuit and a separate circuit for each head signal line.

Description

두개의 테이프에 기록·재생이 가능한 스위칭 회로Switching circuit capable of recording and playback on two tapes

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

Claims (1)

두개의 테이프에 기록, 재생이 가능한 스위칭회로에 있어서, 두개의 테이프 라인(I,II)을 한개의 헤드에 접촉시키고, 상기 헤드에 들어온 기록재생신호를 I라인신호와 II라인신호로 분리하는 것과 헤드신호 스위칭회로(40)로부터 입력된 기록, 재생의 입,출력 두신호를 한개의 4헤드드럼으로 혼합되지 않게 I라인과 II라인에 재생하는 것, 또는 I라인과 II라인에 기록하는 것과, I라인은 재생, II라인은 기록 또는, I라인은 기록 II라인은 재생일때 기록, 재생의 두신호가 간섭하지 않고 기록, 재생을 행할 수 있도록 한 것을 특징으로 하는 두개의 테이프에 기록, 재생이 가능한 스위칭회로.In a switching circuit capable of recording and reproducing on two tapes, the two tape lines (I, II) are brought into contact with one head, and the recording and reproducing signals entered into the head are separated into I-line signals and II-line signals. Reproducing the input and output signals of the recording and reproducing input and output from the head signal switching circuit 40 on the I and II lines so as not to be mixed into one four head drum, or recording on the I and II lines; Line I is for playback, line II is for recording, or line I is for recording. Line II is for playback, so that recording and playback can be performed without interfering with the two signals of recording and playback. Possible switching circuits. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
