摘要:
An optical recording medium is provided which can solve a problem of insufficient signal amplitude of one recording layer as compared with the other recording layer in a writable optical recording medium of a conventional double layer structure. An optical recording medium, in which a first substrate having a first groove formed thereon, a first recording layer formed on a first-groove forming surface of the first substrate, a semi-translucent first reflecting layer, an intermediate layer, a second recording layer, a second reflecting layer, and a second substrate having a second groove formed thereon are at least disposed in this order, wherein the optical recording medium further includes a heat conducting layer between the second recording layer and the intermediate layer and a heat insulating layer between the second recording layer and the second reflecting layer.
