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 evaluation method for calculating an identification signal by using PRML, comprises a table storing true patterns and ideal signals thereof, false patterns corresponding to the true patterns and ideal signals thereof, and Euclidean distance between the true pattern and the false pattern, a calculating unit, when a recording signal synchronized with an identification signal coincides with any pattern of the table, calculates a distance between Euclidean distance between the ideal signal of the true pattern and a reproduction signal and Euclidean distance between the ideal signal of the false pattern and a reproduction signal, and an evaluation unit which evaluates an identification signal by using an average and standard deviation of difference. A table for patterns is created for a likely mistaken pattern, whereby calculating an evaluation value with high precision, of a signal quality, with a small amount of calculation.

摘要： Reproduced signals are equalized by the least square technique by using a predetermined number of data samples binarized by a Viterbi decoder. Even when data written on an optical disk is unknown, the data can be equalized in a stable manner and can be reproduced at a low error rate without instability factors such as divergence due to interference.
