Method of recording and playing back video signals on magnetic tape

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