发明名称 Optical recording medium
摘要 An optical recording medium including two or more recording layers which are capable of transmitting at a high transmittance recording light or reproducing light for performing recording/reproducing of a first recording layer (3) without having to make the thickness of a second recording film (5) positioned towards the side from which the recording light or the reproducing light enters. An optical recording medium including two or more recording layers, and which includes the first recording layer (3), the second recording layer (5) positioned further towards, with an intermediate layer (4) in between, the side from which the recording light or the reproducing light enters than is the first recording layer (3), and includes, between the above-mentioned intermediate layer (4) and the above-mentioned second recording layer (5), a dielectric layer (7) for increasing the transmittance for light passing through the above-mentioned second recording layer as the incident angle of the light becomes greater.
