ABSTRACT:
A digital recording and reproducing apparatus records two kinds of digital signals of an identical video program, generated by high-efficiency coding, or a relatively high bit-rate signal and a relatively low bit-rate signal, onto approximately the same positions on the tape. When the low bit-rate signal is commonly used for normal playback and search-playback or when it is used only for the search-playback, the amount of the search-playback data is adjusted so that data on a number of frames to be a unit for edit work may be recorded onto an integer number of tracks.
