Abstract:
A reproducing apparatus arranged to reproduce a video signal from a recording medium on which a number of recording tracks are formed in parallel with each other and frames of the video signal are recorded on a predetermined number of tracks together with identification information indicative of track numbers of the tracks, a pilot signal component being multiplexed onto the video signal periodically at intervals of four tracks, comprising:(a) transporting means for transporting the recording medium in a direction transverse to the recording tracks;(b) detecting means for detecting a transporting operation of said transporting means to generate a detection signal;(c) reproducing means for reproducing the video signal and the identification information by periodically tracing the recording medium;(d) generating means for generating a periodic signal having a period according to a tracing period of said reproducing means by using the detection signal;(e) deriving means for deriving from the reproduced identification information the track numbers of the tracks;(f) tracking control means for executing tracking control of said reproducing means so that said reproducing means traces one of target tracks which are arranged at intervals of four tracks by using the pilot signal component contained in a video signal reproduced by said reproducing means;(g) determining means for determining a direction of the tracking control by using the periodic signal; and(h) shifting means for shifting the target tracks by only two tracks by changing the direction of the tracking control according to the track numbers derived from the signal reproduced by said reproducing means.
