发明名称 Controlling dynamic tracking heads of digital video tape recorders.
摘要 <p>A dynamic tracking head (HA, HB) of a digital video tape recorder is controlled so as to reproduce a digital video signal of which one field video signal is recorded on a plurality of segmented video tracks (S1 etc.) formed on a video tape (T). The rotational speed of a head drum increased for the heads (HA, HB) to trace precisely the plurality of video tracks forming one field video signal (e.g. i) in a shorter time, thereby to obtain a sufficient time for the video heads (HA, HB) to jump from the end portion of the video tracks to the beginning portion of the next video tracks.</p>
