摘要： A disk-like information recording medium includes recording areas provided in both of a groove portion and a land portion. The information recording medium is divided into groups of a plurality of areas, each track is divided into circular arc-shaped sectors having the same central angle arranged to be radial in the radius direction, identification information is provided at every sector, each track is divided into groups in such a manner that lengths of the circular arc-shaped sectors become almost constant among the groups, and the groove portion and the land portion are wobbled in the radius direction of the information recording medium. When the groove portion information track and the land portion information track which are the recording portions are wobbled in the radius direction, position information can be reliably obtained from the recording portions, and hence recorded information can be accessed reliably. Also, an accuracy with which the rotation of the information recording medium is controlled can be raised, and it becomes possible to position recorded information accurately.

摘要： An optical disk device which improves the S/N ratio of reproduced signals and increases the recording density on it. Pulsed reproducing light is projected onto the data detection points on the optical disk medium to reproduce the data. This enables the reproduction of signals of large optical intensity without raising the temperature of the recording layer. A servo region is irradiated with DC light to form channel clocks from the PLL.

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.
