Abstract

PURPOSE:To search a program swiftly, by recording many kinds of video signals in a lot of channels in a tape, and reproducing a signal of an optional channel by one control track. CONSTITUTION:In a tape T, a video signal of 4 channel portion is recorded in video tracks A-D, and corresponding to there tracks, audio tracks a-d are provided. One of video signals, for instance, to the track A, a control pulse 3 is recorded in a control track. When reproducing, the control pulse 3 is detected by a control head 4, and delay time is varied by a delaying circuit DR. As a result, a servo-circuit S changes the position of a rotary drum 6, changes the trace position of a video head 5, traces a prescribed track among the video tracks A-D, and reproduces it. In this way, a program is searched easily.
