<p>An optical recording medium records information ina mechnism of generating new material, having reflectance different from that of others in information recording layer, when laser beam is projected thereonto. The optical recording medium includes a substrate (60), and a reflective layer (50) positioned on the substrate to reflect an entering laser earn and having an information recording layer (100). The information recording layer (100) includes a first information recording layer (100) containing one or more elements selected form a group of Si, Ge, and Sb, and a second information recording layer (120) containing one or more elements selected forma group of Si, Sb, Te, and Al. Data can be recorded in high density and the optical recording meium provides high recording stability and recording sensitivity.</p> |
