Title: Optical recording medium

Abstract: An optical recording medium comprising, in the following order, a substrate, a reflecting layer, a lower dielectric layer, an optical recording layer, the optical recording layer recording information by means of change in a physical property of the optical recording layer which is generated by an applied light beam, the change in a physical property of the optical recording layer being conducted at an operating temperature, and an upper dielectric layer, wherein the substrate has a thermal deformation temperature lower than the operating temperature and the optical recording medium further comprises a thermally insulating layer between the substrate and the reflecting layer.
