An information storage medium is disclosed comprising a substrate (9), and a recording film (10), formed on the substrate (9), comprising tellurium or tellurium alloy, carbon, and hydrogen, the recording film (10) absorbing far-infrared rays in a wavelength range of 25 to 100 mu m by a chemical bonding of tellurium and carbon having a carbon-hydrogen bond. This information storage medium 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. |
