An optical information recording medium of the present invention includes
a thin film section made up of one or more thin film, the thin film
section being provided on a substrate. Thin films of the thin film
section include a single optical multiple interference film which incites
optical multiple interference in a thin film section, the optical
multiple interference being incited by the change of complex refractive
index in accordance with the intensity of incident light. Also, the
composition and thickness of the optical multiple interference film are
arranged in such a manner as to cause the wavelength distribution of the
reflectance of the thin film section at room temperatures to have a
minimum value within wavelengths of .+-.80 nm of the incident light for
reproduction. With this, the design freedom of the optical multiple
interference film which realizes super-resolution reproduction with a
reduced effective reproduction spot is significantly increased.
