OPTICAL RECORDING MEDIUM BASED ON A TELLURIUM AND ZINC ALLOY

摘要

The invention concerns an optical recording medium comprising an active layer (2) of inorganic material, having one front face (3) for receiving an optical radiation (4) during writing operations, and a rear face (5). The inorganic material is a tellurium and zinc alloy comprising between 60 % and 70 % of zinc and between 30 % and 40 % of tellurium in atomic percentage, preferably 65 % of zinc and 35 % of tellurium. The medium can comprise a semi-reflecting layer (6) arranged on the front face (3) of the active layer and/or an additional metal layer (7) arranged on the rear face (5) and/or a protective polymer layer (8) on the rear face (5). Hence, writing powers, mark resolution and storage density corresponding to DVD format specifications can be achieved.
