Abstract
In a video tape recorder in which a video signal is recorded on a video track, a control signal is recorded on a control track and when reproducing, the control signal is used as tracking signal to control the running speed of the magnetic tape, time is supervised to recognize whether a predetermined period of time expires during the recording pause mode, a cue signal for tape heading is generated at the expiration of the predetermined time or up on change of date, and the thus generated cue signal is recorded on the control track in correspondance to a portion from which recording of individual pieces of information in the video signal starts, thereby making it easy to control edition and heading of the tape.
