SUPPORT D'ENREGISTREMENT OPTIQUE DE DONNEES COMPORTANT UNE COUCHE MINCE EN ALLIAGE D'ETAIN ET TELLURE

摘要

An optical data storage medium comprises at least one active layer of inorganic material, that is able to undergo local deformations during write operations. The active layer presents a front face which is designed to receive an optical radiation at least during read operations. The support also comprises a thin tin and tellurium based alloy layer forming a semi-reflective layer disposed on the front face of the active layer.
