<p>PURPOSE:To cancel inconvenience to be generated in the case of being guard band between tracks in the tracking controller performing the tracking control recording a pilot signal as well as a video signal at the time of recording and using the level of a pilot signal from the adjacent track at the time of reproduction. CONSTITUTION:A pilot signal from among the regenerative signals from a head 2 is supplied to a servo circuit 4, and a voice FM signal is supplied to a voice FM signal AGC circuit 6. In a servo circuit 4, a tracking error signal is prepared and the influence due to the guard band is detected, outputting a detection signal. The AGC detection voltage of the AGC circuit 6 is sent to a tracking control signal preparation circuit 9, and a tracking control signal due to the hiking control is prepared. When a detection signal is outputted, the preparation circuit 9 is operated and the tracking error signal and preparation circuit output are added through a switch 8.</p> |
