To provide an optical recording medium having more simple structure.
An optical recording medium includes a substrate, a cap layer facing the substrate, at least one first recording structure, at least one second recording structure, and a space layer. The first recording structure includes a first recording layer disposed between the substrate and the cap layer, and a reflection layer disposed between the substrate and the first recording layer. The second recording structure includes a second recording layer disposed between the substrate and the cap layer, and Nb2O5 interface layers disposed between the substrate and the cap layer and between the second recording layers. The space layers are disposed between the first and second laminating recording structures, between the first laminating recording structures, and between the second laminating recording structures. One of the first laminating recording structures is directly disposed on the substrate.
