MULTI-LAYER OPTICAL RECORDING DISK |
摘要 |
<p>A multi-layer optical recording medium having a first reflecting film next to an optical incident surface, and a plurality of reflecting films having different optical reflecting characteristics from each other. The first film is formed of two layers which have a large difference of refractive indices. With such a dielectric being used as a first reflecting film, the reflectivity of the first reflecting film is increased, the structure is simple and a multi-layer optical disk with increased storage capacity can be obtained.</p> |
