<p>PURPOSE:To reduce signal absence due to a dropout, etc., and perform precise tracking control by detecting a signal Q and knowing the substantially final position of digital information recorded on a recording medium, and inserting plural pilot signals. CONSTITUTION:If tracking control signals STC having the opposite polarities are detected when the almost center part of some track and the almost center part of a track which is a half drum period later are scanned under tracking servo control, no an actual tracking shift, but the detection of the signal Q is judged. Plural differential amplifiers 61 and 62 as comparing circuits are provided on the output side of a differential amplifier 55 to obtain a concrete detecting means which detects said signal Q. When the signal Q is detected, now another information is recorded from the track following the last recorded track, and then connective shooting is performed without forming any blank track.</p> |
