ABSTRACT:
Digital video tape recorder which operates to receive an advanced television (ATV) signal to be recorded, provide a portion such as a low-band coefficient of an intra-coded frame of the ATV signal as variable-speed data, and record the digital video data and the variable-speed data in a main and a marginal area, respectively, of successive tracks on the record medium in which the marginal area is located on each track at a position which is reproducible in a fast-speed reproducing mode. The digital video tape recorder reproduces the recorded data in the fast-speed reproducing mode by reproducing the portion of the signal stored from the marginal area of each track which is located at specific reproducible areas.
