Abstract

In–SiO₂ cermet films have been studied as optical recording media in metal film ablation memory. Specular surfaces and the minimum writing threshold laser power have been obtained in SiO₂ 40–60-vol.% composition. Pit formation processes have been studied by the temperature bias method, and the use of a trigger layer has been proposed for decreasing the writing laser power. Bi–Pb–Sn–In eutectic alloy and SiO₂ cermet film have also been examined. The 35-mJ/cm² writing threshold laser energy was obtained in this cermet and the phthalocyanine trigger layer construction. Cermet films are stable up to 500°C and are also stable in water.
