| 摘要 |
This optical recording medium is constructed by a substrate, a protecting film, an optical recording material layer, a light reflecting layer and a protecting layer sequentially laminated with each other. The substrate is made of a transparent material. The protecting film is made of transparent optical hardening resin. The optical recording material layer has a transparency reversibly changed in accordance with temperature. The optical recording material layer is formed by an optical recording material in which an organic low molecular substance of higher saturated fatty acid such as stearic acid or behenic acid, etc. is uniformly dispersed in a transparent resin base material composed of thermoplastic resin such as vinyl chloride resin, etc. as a high molecular compound.
