    摘要： An optical disk includes groove tracks (270,272) consisting of a plurality of grooves mutually space apart by a fixed space, and land tracks (271,273) consisting of the areas between the groove tracks, wherein the period of wobbling waveforms of the borders (14,15) between the groove tracks and the land tracks are constant on each border, but the wobbling waveforms of the opposite portions of the borders across the track are shifted in phase by a predetermined phase difference. Information is detected by using a predetermined relation between the the information and the changes in said phase shift.

    摘要： A disk-like information recording medium (8) includes recording areas provided in both of a groove portion (3) and a land portion (4). The information recording medium is divided into groups of a plurality of areas, each track (3, 4) is divided into circular arc-shaped sectors (1) having the same central angle arranged to be radial in the radius direction, identification information (2) is provided at every sector, each track is divided into groups in such a manner that lengths of the circular arc-shaped sectors (1) 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 (3) and the land portion information track (4) 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 information recording method for recording information by forming record marks (6) in a data region of a recording medium (8) such that the information corresponds to both ends of each of the record marks. First and second adjustment or guard regions (22, 25) are provided before and after the data region (23). The lengths of the first and second adjustment regions are changed with the start position of the first adjustment region being changed such that the position of the data region is shifted. In addition, when the same information is recorded a plurality of times, an array of record marks (6) recorded on the recording medium (8) in association with the information includes an array in which the record marks (6) and the spaces (7) between the marks are reversed each other in their positions.
