According to the present invention, an information storage medium is disclosed comprising a substrate, and a recording film, formed on the substrate, comprising tellurium or tellurium alloy, carbon, and hydrogen, the recording film absorbing far-infrared rays in a wavelength rnge of 25 to 100 .mu.m by a chemical bonding of tellurium and carbon having a carbon-hydrogen bond. The information storage medium of the present invention has excellent oxidation resistance and its oxidation resistance can be quickly determined. A method is also disclosed for quickly determining the oxidation resistance of a tellurium film when the method used to manufacture the film is unknown.
