録再生装置。 In a magnetic recording/reproducing device in which a magnetic tape is wound over at least 180 degrees around the outer periphery of a rotating drum to perform guard bandless oblique azimuth recording and reproduce recorded signals, the magnetic tape is wound at intervals of approximately 180 degrees on the circumference of the rotating drum. In addition to the first and second magnetic heads that face each other and have opposite azimuth angle directions, a third magnetic head that is close to the first magnetic head and has an azimuth angle opposite to that of the first magnetic head. The recording head is provided with a head, and when recording or reproducing a digital audio signal, the first magnetic head and the third magnetic head are switched for each rotation of the rotary drum, and when recording or reproducing a composite video signal, the first magnetic head and the third magnetic head are switched. A switching means is provided for switching the second magnetic head substantially every 1/2 revolution of the rotating drum, and when recording or reproducing a composite video signal, the magnetic tape running speed is twice that when recording or reproducing a digital audio signal. Then, the first
and a magnetic recording/reproducing apparatus characterized in that a digital audio signal is recorded or reproduced through a third magnetic head, and a composite video signal is recorded or reproduced through the first and second magnetic heads, respectively.
