    摘要: A hybrid information storage medium includes a lead-in area storing basic information regarding the information storage medium, a lead-out area indicating an end of the information storage medium, and a plurality of types of data areas requiring different optimal read powers, wherein different optimal read power information respectively specifying the different optimal read powers for the plurality of types of data areas are recorded on the information recording medium. Optimal read power information for each of a plurality of data areas of a hybrid super-resolution optical disk requiring different optimal read powers is provided to an optical disk drive when the optical disk drive reproduces data from the hybrid super-resolution optical disk so that optimal reproduction characteristics can always reliably be obtained.

    摘要: A reproducing apparatus is provided. The reproducing apparatus includes a recording/reading unit that records data on or reads data from a disc including a defect management area in which defect information regarding data recorded in a data area of the disc and defect management information for managing the defect information are repeatedly recorded, and a controller that controls the recording/reading unit to read the defect information and the defect management information from the defect management area, and read data from the disc using the defect information. First defect information, which is repeatedly recorded, includes second defect information which is recorded in a predetermined area and defect information regarding a defective block occurring after the second defect information is recorded. The defect management information includes location information of the defect information.
