    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： There is disclosed an information recording medium comprising a guide groove for recording/reproducing information in an information recording region, the information is formed as a recorded mark both in concave and convex portions of the guide groove, management information including address information is recorded by a wobble of the guide groove, and the wobble is formed in such a manner that an offset of a reproducing signal of the recorded mark generated by the wobble of the guide groove is 5.5% or less of an amplitude of the reproducing signal.
