ABSTRACT:
An optical information recording medium uses a nonlinear optical thin film formed on a substrate. The nonlinear optical thin film comprises an amorphous alloy or a mixture of the amorphous alloy and an oxide glass component, and has a refractive index which changes in response to a change of intensity of a laser beam incident thereto.
