ABSTRACT:
A multilayer optical recording medium comprising a substrate, an optional dielectric layer, a first recording layer, a second recording layer, and an optional protective layer. The first recording layer comprises an alloy of a metal and at least one doping element, and the second recording layer comprises a semiconductor. A binary combination of the metal of the first recording layer and the semiconductor of the second recording layer exhibits eutectic phase equilibria.
