摘要：
An optical recording medium includes a substrate, a first dielectric layer, a recording layer, a second dielectric layer, a super-resolution layer, and a third dielectric layer, which are provided in that order. The super-resolution layer is formed of a material configured such that voids are generated when the material is irradiated with DC light at a predetermined irradiation power for 1 to 300 seconds. Therefore, super-resolution reproduction can be made such that the irradiation power of a readout laser beam does not depend on the size of a recording mark.
