ABSTRACT:
An optical recording medium is provided with inorganic bi-layer films that were prepared by magnetic sputtering. A first recording layer containing an element selected from Si or Ge, and a second recording layer contacts with the first recording layer and containing a primary component selected from Ta, Ni or Mo. This optical media can record information by way of microscopic structure changing of bi-layer recording films after laser irradiation.
