ABSTRACT:
A recording/reproduction system performs high precision drop-out processing and compensation in the reproduction mode from a disk-shaped recording medium by using a recording format in which a video signal is divided alternately in units of one horizontal scan line into two channels, and the timing of the recorded video signal on one channel is displaced relative to that of the other channel, so as to record the divided signals on a pair of parallel spiral tracks forming the two channels on the disk. A mean value interpolation circuit is provided in each channel for drop-out compensation, and a portion of a reproduced signal of one channel is compensated by a compensation signal produced by the interpolation circuit of the other channel.
