Optical recording medium, method for manufacturing the same and target used for sputtering process

摘要

An optical recording medium includes a recording layer containing as a primary component an alloy containing at least two elements selected from the group consisting of Fe, Al and Si and the alloy contained in the recording layer as a primary component has a composition Äx1, y1, z1Ü in terms of the ternary composition diagram that falls within a region of a pentagon defined by straight lines connecting points Ä57, 43, 0Ü, Ä0, 55, 45Ü, Ä15, 0, 85Ü, Ä89, 11, 0Ü and Ä0, 16, 84Ü in the ternary composition diagram. According to the thus configured optical recording medium, only minimal load is placed on the global environment.
