    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: A two-layer recording type optical disk capable of realizing stable recording and reproduction without being affected by another recording layer and an optical disk apparatus for the two-layer recording type optical disk are provided. In layouts of various areas in the optical disk, a position where a border between a recorded part and an unrecorded part is formed on one recording layer is set so that the position is always separated from a position where a border between a recorded part and an unrecorded part is formed on another recording layer by a predetermined clearance amount. Moreover, to a recording layer farther from an incident surface, test recording or data recording is always performed through a recorded part on a closer recording layer.
