摘要:
An optical recording medium having two recording layer structures which includes a cover substrate, a grooved substrate, a first recording layer structure, an intermediate layer, a separation layer, and a second recording layer structure. In the optical recording medium, the two recording layer structures include a first recording layer structure, and a second recording layer structure between the substrates, the first recording layer structure includes, in this order, a first protective layer, a first recording layer, a second protective layer, a first inorganic layer, the second recording layer structure includes, in this order, a third protective layer, a second recording layer, a forth protective layer, a second inorganic layer, and a ratio of a thickness of the first recording layer structure and a thickness of the intermediate layer is 0.2 to 1.0.
