An optical recording medium includes a recording layer containing an alloy represented
by a general formula: (TixM1x)yM2y,
where element M1 is Si or Al, element M2 is an element selected from
the group consisting of Si, Al and Fe and different from the element M1,
x is equal to or larger than 0.3 and equal to or smaller than 0.8, and y is equal
to or larger than 0.75 and equal to or smaller than 1.
The thus constituted optical recording medium only places minimal load on the
global environment.
