ABSTRACT:
A recording system adds a track identification (ID) data for identifying each of the slant tracks, in units of GOP, on a tape during the recording of compressed video and audio data. A tape transport is controlled as a function of a longitudinal control signal recorded on a longitudinal track of the tape if a playback control head can normally reproduce the control signal. If, however, the playback control head cannot reproduce the longitudinal control signal, the tape transport is controlled as a function of a slant control signal containing the track ID data previously recorded on the tape. Hence, the tape transport is accurately maintained even if a problem occurs with the playback control head.
