Abstract
PURPOSE:To attain multi-channel recording by applying time axis compression to a video signal of plural channels and applying time division multiplex recording cyclically for a prescribed period. CONSTITUTION:A video signal from tuner circuits 14a, 14b is given to time compression circuits 16a, 16b via AD converters 15a, 15b respectively. The video signal subject to time axis compression is given to a changeover switch 18 and subject to time division multiplex cyclically at a period being the division of the horizontal scanning period by a channel number and recorded on a magnetic tape 5 via a DA converter 19, a recording and reproducing circuit 3 and a rotary head 4. The video signal of the specific channel is reproduced via the rotary head 4, the recording and reproducing circuit 3, the AD converter 25, a time axis expansion circuit 27 and a DA converter 26.
