Abstract

Metallic optical recording layers such as Te are degraded on exposure to oxygen and water. Both oxygen and moisture are necessary for the oxidation of Te to proceed at a significant rate. In this report, the feasibility of protecting thin metal layers from oxidation is examined in light of the known vapor permeability characteristics of selected organic polymeric materials. Experimental results are presented for multilayer Te structures.
