OPTICAL RECORDING MEDIUM AND METHOD FOR MANUFACTURING OPTICAL RECORDING MEDIUM |
摘要 |
<p>An optical recording medium having three or more information recording layers reduces crosstalk caused by multi-reflected beams and improves signal quality. In the optical recording medium having three or more information recording layers, the refractive index of a plurality of intermediate layers disposed between adjacent information recording layers is greater than the refractive index of a cover layer disposed between a light incident surface and an information recording layer being the closest from the light incident surface.</p> |
