ABSTRACT:
A sync signal time difference detection circuit detects a time difference of reproduced sync signals reproduced by a first head and a second head having different azimuth angles. Rotation of a capstan motor is controlled in accordance with sync signal time difference information output from the sync signal time difference detection circuit, thereby performing a highly accurate tracking control not affected by jitter or eccentricity.
