Information recording medium and method for manufacturing the same |
摘要 |
<p>An information recording medium is provided that has high recording sensitivity for recording information and superior repeated rewriting performance. The information recording medium has at least a recording layer that is changeable between a crystalline phase and an amorphous phase by applying a laser beam or electric current and a dielectric layer. The dielectric layer contains at least C, Si, Sn and O. Alternatively, the information recording medium includes at least two information layers with at least one of the information layer including at least a recording layer that is changeable between a crystalline phase and an amorphous phase by applying a laser beam or electric current and a dielectric layer. The dielectric layer contains at least C, Si, Sn and O.</p> |
