Optical recording medium

1. An optical recording medium, comprising:

a resin substrate;

a recording layer comprising an organic dye; and

a reflective layer:

wherein:

the reflective layer comprises a first reflective layer and a second reflective layer in direct contact with the first reflective layer;

the first reflective layer is in direct contact with the recording layer;

the second reflective layer has a thermal conductivity lower than a thermal conductivity of the first reflective layer;

the first reflective layer comprises silver as a main component, and the second reflective layer comprises gold as a main component; and

a film thickness of the first reflective layer is from 60 nm to 200 nm, and a film thickness of the second reflective layer is from 1 nm to 50 nm.

2. The optical recording medium according to claim 1 , wherein the film thickness of the second reflective layer is from 10 nm to 50 nm.

3. The optical recording medium according to claim 1 , wherein the film thickness of the second reflective layer is from 20 nm to 50 nm.

4. The optical recording medium according to any one of claims 1 to 3 , wherein the film thickness of the first reflective layer is from 60 nm to 150 nm.

5. The optical recording medium according to any one of claims 1 to 3 , wherein the medium is capable of recording at a recording linear speed of 28 m/s or higher.
