发明名称 Digital video tape recorder.
摘要 In a digital video tape recording and/or reproducing apparatus including a pair of rotary magnetic heads (13A, 13B) having a predetermined head width and gaps with mutually different azimuth angles which helically scan a magnetic tape (40) as the tape (40) is advanced in order to reproduce digital video signals that have been previously azimuth-recorded in oblique tracks on the tape (40), there is a tape (40) transport means (14) that can transport the tape (40) either at a standard speed or at a non-standard speed. If the tracks recorded on the video tape (40) have a track width equal to the head width, then the tape (40) is transported for reproduction at the standard speed, whereas, if the track width is different from the head width, the tape (40) is transported at the non-standard speed. For example, if the track width is twice the head width, then the tape (40) is transported at twice the standard speed. On the other hand, in another embodiment, when the track width is half of the head width, the tape (40) is transported at a non-standard speed that is one-half the standard speed. <IMAGE>
