PROBLEM TO BE SOLVED: To provide an optical recording medium whose manufacturing stage is simplified compared with a conventional one while higher density can be realized. SOLUTION: The re-writable optical recording medium is characterized in that metal or metal compound super fine particles having 1-50 nm average particle size and a material having 0.5-20.0 W/m.K deg. coefficient of thermal diffusion at 300 K deg. coexist with each other. |
