    摘要: The numbers of times by which plural types of segments are consecutively arranged are limited, an address reading performance is enhanced and address information is correctly read out based on determination of the number of consecutive segments. A track is divided into physical segments, N (=17) wobble data units of constant length are formed in each physical segment, the wobble data unit (WDU) is defined to include a first unit (P) having a wobble modulation portion in a first half portion, a second unit (S) having a wobble modulation portion in a latter half portion and a third unit (U) having no wobble modulation portion, and the physical segment is defined to have segment types (TYPE 1, 2, 3) which each include the third unit (U) in a certain area thereof without fail and respectively include the first, second and a combination of the first and second units in the remaining areas. In the arrangement on the track, a lower-limit number of times M1 by which the first and second types (TYPE1, TYPE2) are consecutively arranged and an upper-limit number of times M2 by which the second types (TYPE2) are consecutively arranged are limited and the first type (TYPE1) and the second type (TYPE2) are respectively arranged immediately before and after the third type (TYPE3).

    摘要: In order to select the latest defect management information, the latest selection information first is selected by searching a plurality of selection information areas for a currently active selection information area in which the latest selection information is recorded and subsequently the latest defect management information is obtained by searching a plurality of defect management areas for a currently active defect management area in which the latest defect management information is recorded. If there is no unused defect management area in which defect management information can be alternatively recorded in lieu of the currently active defect management area, recording operation is limited.

    摘要: The embodiment includes a data replacing area secured in preparation for a defect in a data area, a current DMA set for recording defect management information of a replacement process using the data replacing area, a plurality of unused DMA set areas for replacing a current DMA set, a current DMA managerset area for the current DMA manager set which manages the replacement process using the plurality of unused DMA set, and a plurality of unused DMA manager set areas for replacing the current DMA manager set area. In the unused DMA manager set, there are provided a manager data area describing FFh for showing it is unused, and an identifier area describing 0010h for showing an available manager set.
