ABSTRACT:
An information playback apparatus includes first and second heads which trace a tape on which tracking pilot signals having at least two different frequencies are selectively and periodically recorded with a period of at least 4 tracks, a pilot detector and identifier for generating an identification signal identifying the kind of tracking pilot signal dominantly contained in a playback signal of the first head, and a tracking error detector for detecting and outputting a tracking error signal from tracking pilot signals contained in a playback signal of the second head, wherein tracking control is performed based on the tracking error signal and the identification signal.
