ABSTRACT:
A digital recording and reproducing system, and record carrier for use with the system, in which frames and interframe gaps are recorded in a track on the record carrier. The record carrier has a plurality of longitudinally juxtaposed tracks which each comprises frames and interframe gaps alternating with one another longitudinally along that track. The interframe gaps of adjacent tracks are situated at substantially the same position, viewed in the longitudinal direction of the tracks, and adjacent interframe gaps have substantially the same lengths. In a first embodiment, the interframe gap directly following each frame in each track has substantially the same bit density as that frame. In a second embodiment, the interframe gaps in a track have varying lengths. The recording and reproducing system has recording device for recording the frames and interframe gaps on the record carrier, and a reproducing device for reading the frames from the track.
