摘要： In recording and/or reproducing data into and from a disk record medium having a record medium in which a plurality of tracks are arranged radially, the record area is divided into a plurality of zones, and a clock frequency is assigned to each zone. The data recording and/or reproducing are performed according to the clock of the frequency assigned to the respective zone. Each zone is subdivided to include a plurality of tracks, and a clock having a different frequency is assigned to each zone. Each frequency is set in such a manner that the record capacity of the track gradually becomes larger as the zone is nearer to the outer zone.

摘要： In a method for recording/reproducing information, a reference pattern is recorded in a certain predetermined domain so that the leading-edge and the tailing-edge of a certain recorded portion are positioned in a predetermined relationship, when coded bits of data are recorded on a recording medium by forming recorded portions physically different from not recorded portions, while making them correspond to leading-edges and tailing-edges of the recorded portions. A first and a second reproduced signal indicating the leading-edge and the tailing-edge of the recorded portion, respectively, are detected independently from each other from a reproduced waveform corresponding to the recorded portion, which has been thus recorded; and the first and the second reproduced signal are reconstructed while correcting edge shifts produced at recording data by storing the first and second reproduced signal in a memory, so that the first and the second reproduced signal indicate the leading-edge and the tailing-edge of the recorded portion corresponding to the reference pattern, respectively, in the predetermined relationship.

摘要： A data recording/reproduction method and apparatus uses an optical disk equipped with wobbling track guide grooves disposed in a track scanning direction and minutely wobbled. The apparatus uses a circuit for detecting and correcting displacement of an optical spot position from the wobbling track, and a system for allowing data to correspond to front and rear edges of recording pits as a recording system, and includes a circuit for independently handling reproduction pulses obtained from reproduction signals of the recording pits on the front and rear edge sides and for generating reproduction clocks. A circuit resynthesizes the two series of reproduction pulse trains by a specific pattern portion in the data. Another optical disk apparatus divides each track into zones, and switches a rate of revolution each zone to attain a substantially equal linear velocity. A servo signal reproduction clock generation circuit and a data signal recording/reproduction clock generation circuit are disposed separately. The latter changes a frequency division ratio in accordance with the zones so that a clock having a predetermined frequency can be generated even when the rate of revolution changes.
