<p>PURPOSE:To provide an information reproducing device with excellent responsiveness to tracking drawing and frame synchronizing for a tape multi-segment recording at a high speed. CONSTITUTION:By a drum 2, a head is rotatively scanned, and a regenerative signal is outputted. By a tracking error detection part 4, a tracking error is detected from a tracking pilot signal incorporated in the reproduced signal. By a polarity switching part 5, a polarity of a tracking error signal is switched to be supplied to a tape driving part 6. By the tape driving part 6, the tape feed is adjusted based on the tracking error signal, and the tracking control is performed. By a track number detection part 7, a track number is detected from the reproduced signal. By a polarity setting part 10, the switching polarity of the polarity switching part is set based on the reproduced track number so that the tracking control is stabilized always.</p> |
