Abstract

Phase change optical storage is attractive for several reasons. However, the number of times the media can be reversibly cycled between the amorphous and crystalline state is in general less than magneto-optic media. It is the purpose of this paper to explore the effect of a metal layer on the ability to cycle the recording layer. Experiments were conducted which attempted to separate the thermal effect of the metal layer from other factors. We used ZnS as the capping dielectric, (GeTe)₈₅Sn₁₅ as the recording layer and aluminum as the metal layer.
