An optical recording medium showing a eutectic phase equilibrium (OPTICAL RECORDING MEDIUM EXHI-BITING EUTECTIC PHASE EQUILIBRIA)

摘要

The multilayer optical recording medium 12 containing the substrate 14, the optional dielectric layer 16, the first recording layer 18, the second recording layer 20 and the optional protective layer 22, And at least one doping element, and the second recording layer includes a semiconductor. The binary combination of the metal of the first recording layer and the semiconductor of the second recording layer exhibits eutectic phase equilibrium.
