Abstract

자기기록 재생장치에 있어서, 기록 재생이 동시에 가능하도록 하기 위하여 소정의 각도 및 단차를 가지도록 드럼상에 헤드를 4개이상 장착하고 크로스토크를 줄이기 위해 기록채널과 재생채널이 분리되도록 설게하며, 기록앰프에 의해 오디오 영역만을 편집하도록 하되, 제어신호를 이용하여 오디오 영역에서만 기록하고 믹서에 의해 오디오를 믹싱하여 출력토록 구성되어있다.In a magnetic recording and / or reproducing apparatus, four or more heads are mounted on a drum so as to have a predetermined angle and step so that recording and reproduction can be simultaneously performed, and a recording channel and a reproducing channel are separated to reduce crosstalk, The amplifier is used to edit only the audio area, but only the audio area is recorded using the control signal, and the audio is mixed by the mixer and output.
