Abstract
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.
