SUPPORT D'ENREGISTREMENT OPTIQUE IRREVERSIBLE A BASE D'UN ALLIAGE DE TELLURE ET DE ZINC.

摘要

An irreversible optical recording support incorporates an active layer (2) of inorganic material, presenting a leading surface (3), destined to receive optical radiation (4) during the operations of writing and reading, and a trailing surface (5). The inorganic material is an alloy of tellurium and zinc containing 60-70% zinc and 30-40% tellurium in atomic percentage.
