Description

ABSTRACT:
A recording apparatus, recording/reproducing apparatus or a reproducing apparatus for digital video signals, in which ATV signals, for example, recorded directly on the recording medium, may be easily reproduced with plural varying playback speeds, and in which a playback picture output with spontaneous motion may be achieved even during low varying playback speed. A first area for directly recording the input area, a plurality of second areas for recording data of the input data obtained on intra-picture coding as first data for varying-speed reproduction and a plurality of third areas for recording the motion vector of data of the input data obtained on inter-picture predictive coding as second data for varying-speed reproduction, are provided in each track of the recording medium. The first data and the second data for varying-speed reproduction are repeatedly recorded on a number of tracks of the same azimuth corresponding to the number of speed multiples of the maximum varying playback speed.
