Abstract
A reproducing system for reproducing a video signal from a tape-shaped recording medium on which the video signal is recorded in each of many tracks having different azimuth angles between adjacent tracks includes a reproducing device arranged to use N rotary heads (N: an integer which is at least 2) which have different azimuth angles between adjacent heads and rotate in a closely adjacent state and to reproduce, with the heads, the video signals from N adjacent tracks on the tape-shaped recording medium as N channel video signals, and a monitoring device arranged to monitor the video signals by receiving only M channel video signals (M: an integer less than N) among the N channel video signals.
