Abstract
A magnetic recording/reproducing apparatus includes a plurality of heads attached on a rotary drum, a driver for driving the heads and a tape, head switching circuitry for producing one video signal by switching video signals picked up by the plurality of heads, video signal processing circuitry for processing the video signal produced by the head switching circuitry, and head switching point control circuitry for controlling the head switching circuitry so that the point of the head switching by the head switching circuit is included in the horizontal blanking period of the video signal. The head switching is performed within the horizontal blanking period of the video signal, and therefore no skew due to the head switching is generated in the reproduced video image.
