とする光デイスクプレーヤ。[Claims for Utility Model Registration] To adjust the position of a beam spot for reading information in the tracking direction in an optical disc player that plays back an optical disc on which a plurality of address information is recorded discretely in the longitudinal direction of the recording track. an optical pickup having a tracking adjustment means, and during a seek period in which the optical pickup is moved at high speed in the radial direction of the optical disk, the position of a beam spot for reading information from the optical pickup is determined as recorded on the optical disk. From the point when the track reaches an area slightly before the recording area of one address information, the tracking adjustment means of the optical pickup is driven based on a signal corresponding to the moving speed of the optical pickup and the eccentricity of the optical disk. An optical disc player characterized in that the beam spot is moved along the recording area of the one address information.
