Abstract:
Disclosed herein is an optical recording medium, including: a substrate; and an information recording layer formed on the substrate, an information signal being recorded and reproduced in and from the information recording layer by radiation of a light; wherein the information recording layer includes a reflecting layer, a dielectric layer formed on the reflecting layer, and a recording layer formed on the dielectric layer, the dielectric layer includes a first dielectric layer and a second dielectric layer, and a thermal conductivity of the second dielectric layer located on the reflecting layer side is higher than that of the first dielectric layer located on the recording layer side.
