Abstract

PURPOSE:To make a recording signal and a reproducing signal into a wide band area and to obtain an image with high resolution, by recording a video signal by dividing time-divisionally into plural tracks and restoring it to an original video signal by converting them to a time series signal via a synthesizing means at the time of reproduction. CONSTITUTION:A recording system 26 and a reproducing system 27 are connected to magnetic heads 13 and 14 via change-over switches 11 and 12, and switching to the recording system 26 or to the reproduction system 27 is performed by a switching signal H. At the time of recording a signal, the recording signal is bi-sected corresponding to the number of heads (in the example, 2) by passing it through sample-hold circuits 3 and 4 which function as time division means, and they are recorded time-divisionally on two tracks in order by the heads 13 and 14. Therefore, it is possible to expand a frequency band area by double of conventional area at the time of recording the signal. At the time of producing the signal, the signal is restored to its original video signal by converting the output of the heads 13 and 14 to the time series signal via the synthesizing means of the signal reproduction system 27, and is outputted to a monitoring device.
