ABSTRACT:
Digital video tape recording apparatus of the type which converts a vertical interval of picture data into image blocks of digital picture element data that is compression encoded and recorded on video tape which is selectively driven at first or second speeds, wherein the second speed is approximately 1.5 times faster than the first speed. The digital video recorder includes two rotatable transducers disposed approximately 180.degree. apart, each transducer having a recording gap length, or head width, for recording a track pitch, the gap length being at least equal to the track pitch that is recorded when the tape is driven at the second speed. The transducers have respectively different azimuth angles to minimize crosstalk interference during playback.
