Abstract
Abstract An apparatus for recording and/or reproducing a signal on a tape recording medium with a plurality of rotary recording and/or reproducing heads includes a first input and/or output terminal for receiving and/or deriving a video signal, a second input and/or output terminal for receiving and/or deriving an audio signal, and a recording and/or reproducing circuit including a rotary transfer. A first rotary recording and/or reproducing head is connected to the first input and/or output terminal through the recording and/or reproducing circuit and records and/or reproduces the video signal on first parallel slant tracks of a tape recording medium. A plurality of second rotary recording and/or reproducing heads are connected to the second input and/or output terminal through the recording and/or reproducing circuit and record and/or reproduces the audio signal on second parallel slant tracks of the tape recording medium. A plurality of the second parallel slant tracks are then formed corresponding to one of the first parallel slant tracks.
