ABSTRACT:
This invention relates to an information-recording medium that is used for recording information through radiation of energy beam. The information recording medium has a groove-shaped information recording track and is provided with a recording layer, one or more kinds of heat sink control layers and heat sink layers. A sum of film thickness of the more than one kind of recording layer is equal to or less than a step between information recording tracks, and a sum of film thickness of one or more kinds of heat sink control layers is more than a groove depth of the information recording track. With this configuration, no cross-erase is produced even if the information-recording medium is applied for a high density recording with the track pitch being 70% or less.
