ABSTRACT:
An optical disc drive apparatus includes a rotatably supporting drive unit supporting an optical disc, an optical pickup, an angular velocity sensor detecting the magnitude and direction of an angular velocity, a skew estimating section estimating disc skew from the result of detection by the angular velocity sensor, such that one estimated skew value in a case where the angular velocity is applied in a direction in which the optical disc moves away from the optical pickup differs from another estimated skew value in a case where the angular velocity of the same magnitude but in the opposite direction, in which the optical disc approaches the optical pickup, is applied, and a tilt drive section changing the tilt of the light beam in accordance with the estimated skew value and correcting a shift, occurring because of the angular velocity, in a light beam applying position on the optical disc.
