Abstract

An optical recording media includes a substrate, a cap layer opposite to the substrate, at least one first stacked recording structure, at least one second stacked recording structure, and a space layer. The first stacked recording structure including 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 is disposed between the substrate and the cap layer. The second stacked recording structure including a second recording layer disposed between the substrate and the cap layer and an Nb2O5 interface layer disposed between the substrate and the second recording layer is disposed between the substrate and the cap layer. The spacer layer is disposed between the first and second stacked recording structures, the first stacked recording structures, and the second stacked recording structures. One of the first stacked recording structures is disposed directly on the substrate.

Dependent claims

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 (Nb2O5) interface layer, disposed between the substrate and the second recording 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.
