摘要： PROBLEM TO BE SOLVED: To provide a method and a device capable of satisfactorily initializing two recording layers in a short period of time.
SOLUTION: The rotational speed of an optical disk 21 is changed in accordance with the radial position of an initializing laser spot while two initializing spots 19 and 20 simultaneously converged on two layers are fed in the disk radial direction by different predetermined functions. Thus, different initialization laser spots suited to the recording layers are obtained on the full surface of the optical disk, and thereby good initialization is executed on the two recording layers within a short time. Especially, the scanning speed ratio and the radial feeding amount ratio of the laser spots are set to predetermined values before the execution of the initialization. During the execution of the initialization, the spot radial position (radius) is controlled to be equal in ratio to the scanning speed ratio or the radial feeding amount ration.
