ボ機構。 An optical pickup equipped with an objective lens facing the recording surface of an optical disk placed on a turntable is provided to move in the radial direction of the optical disk. In an optical disc player, the optical disc player is equipped with a sensor that detects a tilt state in the radial direction, and a correction drive unit that changes the tilt attitude of an optical pickup based on a detection signal from the sensor. An optical disc player characterized in that a plurality of the correction drive parts are fixedly provided facing the surface and spaced apart from each other in the radial direction of the optical disc, and the correction drive part is driven according to detection signals from the plurality of sensors. tilt servo mechanism.
