Patent ID: 8420198

Claim:
An optical recording media, comprising: a substrate; a cap layer, disposed opposite to the substrate; at least one first stacked recording structure, disposed between the substrate and the cap layer, each of the first stacked recording structures comprising: a first recording layer, disposed between the substrate and the cap layer; and a reflective layer, disposed between the substrate and the first recording layer; at least one second stacked recording structure, disposed between the substrate and the cap layer, each of the second stacked recording structures comprising: a second recording layer, disposed between the substrate and the cap layer; and a niobium oxide (Nb 2 O 5 ) interface layer, disposed between the substrate and the second recording layer, wherein the Nb 2 O 5 interface layer serves as a reflective/dielectric layer; and a space layer, disposed between the first stacked recording structures and the second stacked recording structures, between the first stacked recording structures which are adjacent to each other, and between the second stacked recording structures which are adjacent to each other, wherein one of the at least one stacked recording structure is directly disposed on the substrate.
