MAGNETIC RECORDING/REPRODUCING DEVICE

PURPOSE:To make video information, and audio information of a long play coexist in one magnetic tape by running the magnetic tape at a lower speed than a running speed of a regular time, and shifting successively a switching phase of a rotary head by a prescribed quantity. CONSTITUTION:In case of recording a PCM audio signal after having recorded a video signal to the middle of a magnetic tape 4, a control means 7 switches a switch 1 to the lower side in the figure, and outputs a PCM audio signal to a rotary head 3. Also, the tape 4 is run in the forward direction at a lower speed than a regular case, for instance, at a speed of 1/6. Also, the means 7 generates a pulse of width of integer multiple of length of an area, in a position which has advanced by the time corresponding to length of one area from a rise edge of a head switching pulse. In case of the next rise edge, a phase id delayed by width of its pulse, comparing with the case of the previous time. As a result, the PCM audio signal is recorded successively in the trace direction, in sections H, I and J, and sections K, L and M by a rotary head A and a rotary head B, respectively.
