A pickup moving mechanism in which a discrepancy between the optical axis (3a) of an optical pickup (3) and an object position on the disk hardly occurs. The mechanism comprises a lifting member (20) adapted to swing guide members (4, 5) on the basis of a disk-radius-wise angular deviation of the optical axis (3a) of the optical pickup (3) to tilt the optical pickup (3) supported by the guide members (4, 5) in a direction to minimize the angular deviation of the optical axis (3a), a cam follower (20c), a tilt motor (21), an eccentric cam (22), an urging means (24), and a control means for controlling a pickup motor (6) which actuates a screw member (7) and an engaging member (10) in such a manner as to move the optical pickup (3) in a direction to minimize the disk-radius-wise deviation of the optical axis (3a) caused by the inclination of the pickup disk (3).
