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： An optical disc, 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： 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： A novel recording medium capable of realizing high density, reliability in a recording/reproducing operation and facilitating the process which is performed by a drive apparatus is provided. An amplitude amount of wobbling of a track is made to be 10 nm to 15 nm and a track pitch of the track is made 0.74 &mgr;m to 0.82 &mgr;m. The determined values enable large-capacity recording to be realized and the recording/reproducing performance to be prevented from being deteriorated. As administration information, recommended information for a recording/reproducing operation at an inner peripheral position and an outer peripheral position is recorded. The size of data in a linking section is made to be the same as the sector for constituting a data block.

摘要： Thermal stress is prevented from accumulating on a disk recording medium. Data to be recorded is divided into 32-kilobyte clusters, and a front link area and a back link area, whose lengths are randomly changed, formed of a total of 8 frames are added before and after the clusters. Then, the data is recorded on a predetermined area of a disk on the basis of address data prerecorded on the disk.
