INFORMATION RECORDING MEDIUM, DEVICE AND METHOD FOR RECORDING INFORMATION, AND DEVICE AND METHOD FOR REPRODUCING INFORMATION

摘要

Provided is a multilayer-recordable information recording medium with which highly-accurate tracking servo control is performed while employing the zoned-CAV mode, and with which a specific type of process, such as highly-accurate tilt detection, is performed while having enhanced information recording density. The disclosed zoned-CAV-mode information recording medium (11) includes: a guide layer (12) having tracks (TR) formed therein in advance; and a plurality of recording layers (13) laminated on the guide layer. The tracks include a plurality of guide regions (22) each having a physical structure that carries guide information for the purpose of guiding. The guide regions are arranged discretely along the track direction at intervals of less than or equal to a predetermined distance that has been defined in advance, and, over a plurality of said tracks that are adjacent to one another in the radial direction, the guide regions are misaligned from one another among the plurality of tracks. The tracks are segmented along the track direction into a plurality of slots, and said guide regions are arranged in some of said slots that are not adjacent to one another in the track direction and that are not adjacent to one another over a plurality of said tracks in the radial direction.
