摘要： Optical discs are adapted to be used with a light beam having a wavelength of 405 nm for recording or reproducing data. Error correcting blocks for recording BMID including copy protection key information are defined on optical discs (1) dedicated to data reproduction. A data string of BMID to be recorded has 64 bytes. An error correcting block is constituted by 304 columns of error correcting code words (LDC). A BMID data string of 64 bytes is inserted to predetermined 64 error correcting code words (LDC) of a block (304 columns of error correcting code words). The total code length of the predetermined 64 error correcting code words (LDC) is 248 bytes, of which a predetermined byte (symbol) is replaced by a predetermined byte (symbol) of the BMID data string.

摘要： An ECC block is constituted by RS(248,216,33). Of a data length of 216 bytes (symbols), only 16 bytes are allocated to BCA data and the remaining 200 bytes are used for fixed data having a predetermined value. Using the fixed data of 200 bytes and the BCA data of 16 bytes, parities of 32 bytes (symbols) are calculated. Only the BCA data of 16 bytes and the parities of the former 16 bytes of the 32-byte parities, that is, a total of 32 bytes only, are recorded in a burst cutting area of an optical disc. In decoding, error correction processing is carried out by using the fixed data of 200 bytes. The unrecorded parities of 16 bytes are processed as having been erased. Thus, the error correction capability in a burst cutting area of an optical disc can be improved.

摘要： In step S1, the address generator generates address information composed of a sync signal which is recorded on an optical disc, address data and an error correction code for the address data, pre-encodes and supplies it to a modulator. At the same time, a carrier signal generator generates a carrier signal which is to carry the address information, and supplies it to the modulator. In step S2, the modulator makes MSK modulation of the carrier signal supplied from the carrier signal generator on the basis of the pre-encoded address information supplied from the address generator, and supplies a resultant MSK modulation signal to a wobbling unit. In step S3, the wobbling unit forms, on the optical disc, a spiral groove wobbled adaptively to the MSK modulation signal supplied from the modulator. In this optical disc, a given address can be accessed quickly and accurately.

摘要： With the disc-shaped recording medium, or the disc manufacturing method according to the present invention, for both the single-layer disc and the multi-layer disc, a recording layer L0, which is to be the first layer, is at the same distance, along the direction of disc thickness, from the surface of the cover layer CVLs on which falls the laser light. For the multi-layer disc, the second layer L1 and the following layer(s) are formed at the locations which are closer to the cover layer CVLs than the first layer L0. Management information may be recorded by mobbling grooves, each layermay have tert areas, defect information, a replacement area. Thus, it is possible to improve compatibility, reliability and accessibility between a single-layer disc and a multi-layer disc. The spherical aberration for the recording/reproducing light may be controlled with respect to the selected layer.

摘要： An information recording/reproducing apparatus wherein exact reproduction of both wobbled address information and sync information can be realized in a recording mode as well as in a reproduction mode. The apparatus comprises first and second detectors for detecting two diametrical side portions of each track on a recording medium where a pregroove is modulated correspondingly to address information and sync information of mutually different frequency bands; a calculator for calculating a normalized track information signal on the basis of the outputs of the first and second detectors; and a third detector for detecting the address information and/or the sync signal on the basis of the output of the calculator.

摘要： It is an object of the present invention to realize a data recording disk that is resistant against burst errors and capable of quick access without sacrificing recording capacity. A disk 1 is divided into zones, and the number of sectors per track is made larger by one in a more outside zone than in a more inside zone. The disk 1 is driven at a constant rotational angular velocity. The sector is composed of an address area and a data area, and it is arranged for the address recorded in the address area to complete error detection and correction processing within the address area. An error detection and correction code in the data area is completed extending over a plurality of sectors.
