An optical recording medium includes a substrate, a first recording layer
formed on the substrate and containing an element selected from the group
consisting of Si, Sn and Ge as a primary component, and a second
recording layer located in the vicinity of the first recording layer and
containing Ag as a primary component, the optical recording medium being
constituted to be irradiated by a laser beam projected onto the side
opposite from the substrate. According to the thus constituted optical
recording medium, it is possible to decrease a noise level and improve a
C/N ratio in a reproduced signal.
