    摘要: In a recording medium including stacked recording layers, management data requiring reliability is recorded in the recording layer far from the surface of the recording medium and data bodies are recorded in the recording layer close to the surface of the recording medium. Thus a data file can be read even if defects such as fingerprints and scratches occur on the surface of the recording medium.

    摘要: After an optical disk drive according to the present invention has been loaded with an optical disk and before the operation of recognizing the type of the given disk is finished, the drive presumes one of multiple types of candidate optical disks, from/on which data is readable and writable using a light beam with the shortest wavelength among the candidate disks, to be the disk being driven by the motor now and gets the beam for the presumed type of disk radiated from a light source (Step (A)). Next, the drive gets the disk spun at a rotational velocity that realizes a linear velocity equal to or higher than a standardized normal velocity when data is read from the presumed type of disk (Step (B)). Thereafter, the drive starts a focus control in a situation where the spot of the beam being formed on the disk is moving on the disk at the linear velocity equal to or higher than the normal velocity (Step (C)). And then the drive performs the operation of recognizing the type of the disk by the light beam reflected from the disk under the focus control (Step (D)).
