INFORMATION RECORDING MEDIUM, INFORMATION RECORDING APPARATUS AND METHOD, AND INFORMATION REPRODUCING APPARATUS AND METHOD

摘要

An information recording medium adopting a zone CAV method is provided with: a guide layer in which tracks are formed in advance; and a plurality of recording layers laminated on the guide layer. On the tracks, a plurality of guide areas, each of which has a physical structure for carrying guide information for guidance, are arranged discretely at arrangement intervals of predetermined distance or less which is set in advance in a track direction and are shifted between a plurality of tracks throughout the plurality of tracks which are adjacent to each other in a radial direction. On the tracks, moreover, a plurality of specific areas, each of which has a predetermined pattern, are respectively arranged in a same phase from an inner circumference to an outer circumference in the radial direction such that the predetermined pattern can be detected in a state in which tracking servo is open.
