An optical recording medium records information in a mechanism 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, and a reflective layer positioned on the substrate to reflect an entering laser beam and having an information recording layer. The information recording layer includes a first information recording layer containing one or more elements selected from a group of Si, Ge, and Sb, and a second information recording layer containing one or more elements selected from a group of Si, Sb, Te, and Al. Data can be recorded in high density and the optical recording medium provides high recording stability and recording sensitivity.
