    • 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.
    • 为了在磁带上记录和播放视频信号,磁带被馈送通过磁头并周期性地反转。 使用固定的多磁道磁头,磁带相对移动。 根据前进行驶中的电路技术,多轨头的头部间隙依次分配给半画面的线。 在这种情况下,通过间隔扫描以非常窄的短非重叠逐步平行轨道的形式记录半图像,并且在回放期间被再现。 在磁带的向后移动期间,磁头间隙然后以相反的顺序被分配给半图像的行,使得轨道序列在每次反转期间被移位至少一个间隙。 轨道序列末尾缺少的间隙由头列间隙另一端的相应数量的间隙循环组成。
