Optical disc apparatus
2003
Means for rotating the optical disc comprises a disc (1) of the disk motor (114), along a disc (1) move the beam in the radial direction of the optical disc (1) irradiating a beam spot on the lateral movement (111), for detecting linear beam spot velocity linear velocity calculating means (117) for the disk motor control means (116) controls the disk motor (114), such that the recording information read line speed on the operation member (1) an optical disk (117 ) detected by the linear velocity of the optical disc (1) at any radial position remains substantially constant, the search control means (121), and for controlling the lateral movement (111) to prevent lateral movement (111) moving the beam spot lines speed is reduced to the permissible linear velocity or below the position distribution adjusting member (118).
