RECORDING LAYER FOR OPTICAL INFORMATION RECORDING MEDIUM, OPTICAL INFORMATION RECORDING MEDIUM, AND SPUTTERING TARGET FOR OPTICAL INFORMATION RECORDING MEDIUM |
摘要 |
Provided is a recording layer for optical information storage media, which not only excels in initial reflectivity and creativity of recording marks, but also extremely excels in durability under high temperature and high humidity conditions, and which can be adequately applied to next-generation optical discs using blue-violet laser. The recording layer for optical information storage media is a recording layer to create recording marks upon irradiation with a laser beam. This recording layer is composed of a tin-based alloy containing a total of 1.0 atomic percent or more and 15 atomic percent or less of at least one selected from neodymium (Nd), gadolinium (Gd), and lanthanum (La).
