INORGANIC OPTICAL RECORDING MEDIUM COMPRISING A HEAT DISSIPATION LAYER

摘要

The invention concerns an optical recording medium comprising an active layer (2) of inorganic material, adapted to be deformed under the effect of an optical radiation, having a front face (3) for receiving an optical radiation (4) during writing operations and a rear face (5). An additional metal layer (6) is arranged on the rear face (5) of the active layer (2). The additional metal layer (6) preferably has a thickness ranging between 9 nanometers and 12 nanometers. The inorganic material of the active layer (2) may be a tellurium and zinc alloy comprising between 60 % and 70 % of zinc and 30 % and 40 % of tellurium in atomic volume, and preferably 56 % of zinc and 35 % of tellurium. The medium may comprise a semi-reflecting layer (7) arranged on the front face (3) of the active layer (2) and/or a polymer protective layer (8) on the rear face (5).
