Abstract
In an apparatus for digitally recording and reproducing video and audio signals in successive parallel slant record tracks on a record tape; pluralities of recording heads are mounted on a rotary drum at diametrically opposed positions so that one field of a video signal is recorded in a plurality of the tracks scanned by the recording heads as the record tape is advanced at a predetermined speed, a pair of bimorph leaves are mounted at respective opposed positions on the rotary drum, a plurality of reproducing heads are disposed on each of the bimorph leaves to be deflected by the respective bimorph leaf in a direction transverse to the direction along the record tracks when, in a reproducing mode, the tape is advanced at a speed different from the predetermined speed used for recording, and the number of the reproducing heads is greater than, for example, twice, the number of the recording heads for relatively reducing the maximum deflections of the reproducing heads by the bimorph leaves needed to achieve substantial tracking of the record tracks while the tape is advanced at such different speed.
