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 [x1, y1, z1] in terms of the
ternary composition diagram that falls within a region of a pentagon defined by
straight lines connecting points [57, 43, 0], [0, 55, 45], [15, 0, 85], [89, 11,
0] and [0, 16, 84] in the ternary composition diagram.
According to the thus configured optical recording medium, only minimal
load is placed on the global environment.
