Abstract
In order to record and play back video signals on magnetic tape, the magnetic tape is fed past a magnetic head and reversed periodically. A stationary multi-track magnetic head is used, and a magnetic tape moves relatively thereto. The head gaps of the multi-track head are successively allocated to the lines of a half-picture in accordance with circuit technology during forward travel. In this case, the half-picture is recorded by gap-wise scanning in the form of very narrow short non-overlapping stepwise parallel tracks and is reproduced during playback. During backwards travel of the magnetic tape, the head gaps are then allocated to the lines of the half-picture in the reverse sequence so that the track sequence is shifted by at least one gap during each reversal. The gaps missing at the end of the track sequence are made up cyclically by the corresponding number of gaps at the other end of the row of head gaps.
