简介 PROBLEM TO BE SOLVED : To provide a recording layer for optical information recording medium which is excellent in writing and reading characteristics and reflectance characteristics and which can be applied to a next-generation optical disk, to provide an optical information recording medium, and to provide a spattering target which is useful for forming the recording layer. SOLUTION : The optical recording layer for optical information recording medium formed by irradiation with a laser beam, wherein the recording layer comprises an In-based alloy containing 0.1-15% of at least one rare earth element, 0.1-50% of one element selected from among Pd, Co, Pt and V, 6-50% of Ni, or not less than 0.1% and less than 50% of Au. The recording medium has the recording layer. The spattering target comprises the same alloy composition as is used in the formation of the recording layer. COPYRIGHT : (C)2007, JPO&INPIT
