摘要： An optical disc having address information recorded in a wobbling manner is arranged to record or reproduce data at correct positions. A track is previously formed as a pregroove and is wobbled in accordance with address information. The track is divided into a plurality of sectors. A plurality of sync marks S are formed in each sector, and at least one of the sync marks in one round of the track is formed as a reference mark R different from the other sync marks S. To reduce overhead and to achieve highdensity random recording and reproduction, a method may also be used in which one cluster of data is formed of a data area and a link area located between data areas and consisting of two frames, in which each of the data area and the link area has a structure formed of unit frames separated by a sync signal (frame sync), and in which data is recorded or reproduced as unit clusters.

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： 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.
摘要翻译： ECC块由RS（248,216,33）构成。在216字节（符号）的数据长度中，只有16字节被分配给BCA数据，剩余的200字节用于具有预定值的固定数据。使用200字节的固定数据和16字节的BCA数据，计算32字节（符号）的奇偶校验。只有16字节的BCA数据和32字节奇偶校验的前16个字节的奇偶校验，即仅总共32个字节的奇偶校验数据被记录在光盘的突发切割区域中。在解码中，通过使用200字节的固定数据来执行纠错处理。 16字节的未记录奇偶校验被处理为已被擦除。因此，可以提高光盘的突发切割区域中的纠错能力。

摘要： First error-processing data are generated with respect to a predetermined amount of data, and second error-processing data are generated with respect to each of a plurality of blocks produced by dividing the predetermined amount of data. Data of record units are generated from the predetermined amount of data, the first error-processing data, and the second error-processing data. The data of record units are recorded on and reproduced from a recording medium. Errors are corrected in the predetermined amount of data in the reproduced data of record units with the first error-processing data with respect to each of the record units. If errors cannot be corrected, at least errors are detected in the predetermined amount of data in each of the blocks with the second error-processing data. If errors are detected in N (N is a positive integer) successive blocks, all data in at least one block which is not positioned at an end of the N successive blocks are regarded as being erased, thereby correcting errors in the predetermined amount of data in the record units with the first error-processing data, thus producing reproduced data.

摘要： An optical dick, an apparatus and a method for recording/reproducing the optical disk use Gray coded address information. The hexadecimal data 0 to F correspond to the Gray codes. The Gray code consists of the upper address and the lower address. The four channels of the upper address and the four channels of the lower address are set so that one channel of each address is "1". With the change of the data from 0 to F, the channel of "1" in the lower address sequentially moves to the adjacent channel in the corresponding Gray code. Consequently, rapid seeking can be performed by detecting only the lower address.

摘要： A method of recording data on a disc on a disc pre-recorded with servo control data, with the servo control data being pre-recorded in the form of convex and concave pits at intervals along substantially concentric tracks, the servo control data recorded in alignment in a diametrical direction of the disc. The method includes the steps of dividing the disc into a plurality of zones in the radial direction, dividing the tracks into a plurality segments such that there is an equal number of segments in each interval between adjacent pre-recorded servo control data. The method further includes the step of recording reference data on at least one segment of the plurality of segments in each interval between adjacent servo control data, with the reference data being utilized to adjust a gain and a phase of a read-out clock upon reproduction of the disc. The method further includes the step of recording digital data on at least one segment of the plurality of segments in each interval between adjacent servo control data, with the digital data being recorded at a constant angular velocity and with the constant angular velocity being different for each zone.
