Title:
INFORMATION RECORDING MEDIUM, INFORMATION RECORDING DEVICE AND METHOD, AS WELL AS INFORMATION PLAYBACK DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2011/158376
Kind Code:
A1
Abstract:
In a multilayer recording type information recording medium, such timing information as of a recording-use synchronous clock is generated with high precision while adopting the CLV method. A CLV-type information recording medium (11) is provided with a guide layer (12) upon which tracks (TR) have been formed beforehand and a plurality of recording layers (13) which are layered upon the guide layer. In the tracks, a plurality of guide areas (22), each having a physical structure for carrying timing information for recording in the recording layers as one type of guide information for guide-use, are placed adjacent in phase in a radial direction across a plurality of tracks, so as to be staggered among the plurality of tracks, discretely at placement intervals of a predetermined distance or below which have been set beforehand in the track direction.
