摘要： According to one embodiment, a first encoder encodes main information, a second encoder encodes sub-information, a first modulator modulates a carrier based on an output of the first encoder, a duplicating module duplicates an output of the second encoder to generate encoded sub-information units, and a second modulator amplitude-modulates an output of the first modulator based on the encoded sub-information units. The second modulator amplitude-modulates with σ/(μ×(2N)1/2) being 0.4 or less, wherein a noise power of a transmission path or a storage medium is σ2, a number of the encoded sub-information units is N, signal levels after amplitude modulation, which correspond to bit 1 and bit 0 of the encoded sub-information units, are A and B, and a level difference A−B is μ.

摘要： Address information is formed by M wobbles (integer M is the number of wobble waves) per bit as a basic unit, and is NRZ-recorded. Also, a sync signal used in sync detection of the address information is formed by N wobbles per bit as a basic unit (integer N is the number of wobble waves and M=2N). The sync signal with such configuration (6 wobbles per bit) is recorded on the head side of the address information (12 wobbles per bit). In this way, even when external noise is large, a modulated wobble signal can be demodulated more accurately.

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).
