The reference light beam irradiation unit comprises a diffusion board provided in the way of a light path through which the laser beam is passed and generating the reference light beam, a rotation controller to rotate the diffusion board, and an identification information detector to detect identification information previously formed on a surface of the diffusion board. The diffusion board comprises a plurality of encode storage regions in which different identification information is formed and a plurality of diffusion pattern generation regions specified by the identification information. A position of the diffusion board is controlled based on the detected identification information such that a desired diffusion pattern generation region comes to a position through which the laser beam is passed while the laser beam is outputted.

摘要： An error correction device error corrects without increasing in circuit scale. An encoder, includes: a first ECC encoder which interleaves a data string into n (n≧2) blocks of data strings at every m (m≧2) bits, and adds the error correction code parity; a parity encoder which creates a parity bit at every plurality of bits of the error correction code word, and adds the parity bit to said error correction code word; and a second ECC encoder, which generates a second error correction encoding, which is a linear encoding using iterative decoding. Concatenated type encoded data, where a parity bit is added to every plurality of bits, is created, so an increase of circuit scale can be prevented even if a data string is interleaved into a plurality of blocks and error correction code parity is generated.

摘要： It is an object of the present invention to provide a data reproducer in which the quality of a reproduction signal is improved. A data reproducer of the present invention includes a phase-difference detecting section which obtains the cross correlation value between the head pattern in a track to be reproduced and a reproduction signal, synchronous detectors which respectively obtain the cross correlation value between the head pattern of a track adjacent to the track to be reproduced and the reproduction signal, and crosstalk value detector which obtains the direction and ratio of crosstalk in accordance with these cross correlation values. The data reproducer has a correcting function which corrects the offset and gain of a reproduction signal in accordance with a phase difference and cross correlation value obtained by the phase-difference detecting section.
