ABSTRACT:
A tape position data recording and reproduction method whereby the start points of all programs recorded on the tape can readily be determined merely by playing the tape for a very short time in the reproduction mode. Position data related to a present program and position data related to all subsequent programs are repeatedly recorded at predetermined positions in digital data recording tracks, which are provided as extensions of the tracks containing the video signal. Once the numerical value indicative of the start position of the desired program has been determined, the tape can readily be advanced to that point.
