Multiplex rotating magnetic head system for multiply recording and erasing audio and video signals |
摘要 |
A multiplex recording/reproducing system with at least four video signal recording/reproducing magnetic heads mounted on a rotating body with a predetermined interval in the direction of rotation of the rotating body. At least four audio signal recording/reproducing magnetic heads are mounted on the rotating body, alternately with the video signal recording/reproducing magnetic heads. The magnetic tape is forwarded while being wrapped on the rotating body over a region extending at least a multiple of the predetermined interval. Recording/reproducing circuits record and reproduce the video signal and the audio signal while switching over the video signal and the audio signal recording/reproducing magnetic heads in a predetermined order for every predetermined period. An erase signal is supplied to at least one of the audio signal recording/reproducing magnetic heads, which is disposed preceding to the video signal recording/reproducing magnetic head, which records the video signal on a magnetic tape track, during a period of time where no audio signal is supplied thereto.
