| 摘要 |
An information recording medium comprising a substrate, a phase-change type recording layer and capable of storing information therein through a phase-change of a portion thereof upon being irradiated by light beam, a first dielectric protecting layer interposed between the substrate and the recording layer, a second dielectric protecting layer formed on the recording layer, a first light-absorptive protecting layer comprising a dielectric material and at least one material selected from metals, semimetals and semiconductor materials and interposed between the recording layer and the first dielectric protecting layer, and a second light-absorptive protecting layer comprising a dielectric material and at least one material selected from metals, semimetals and semiconductor materials and interposed between the recording layer and the second dielectric protecting layer.
