    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： An attempt is made to make it possible to efficiently perform the finalizing process and closing process in a short period of time. When the border closing or finalizing process is performed after user data is recorded, latest recording management data (RMD) is recorded in a recording management data duplication zone (RDZ) of a data lead-in area, latest recording management data (RMD) is recorded in an unrecorded area of a present recording management zone (RMZ) and R physical format information (R-PFI) is recorded in an R physical format information zone (R-PFIZ) in a first step and a padding process is performed for at least a discontinuous area in the data area and a border-out is lastly recorded in a second step.

    摘要： An attempt is made to make it possible to efficiently perform the finalizing process and closing process in a short period of time and securely manage the last address of a border-out. When the border closing or finalizing process is performed after user data is recorded, a padding process is performed for at least a discontinuous area in the data area and a border-out is lastly recorded in a first step. Then, in a second step, latest recording management data (RMD) is recorded in a recording management data duplication zone (RDZ) of a data lead-in area, latest recording management data (RMD) is recorded in an unrecorded area of a present recording management zone (RMZ) and R physical format information (R-PFI) is recorded in an R physical format information zone (R-PFIZ).
