ABSTRACT:
A simple method for evaluating an optical information medium by judging quantitatively and reproducibly the surface quality of the optical information medium by the use of an artificial fingerprint liquid as an evaluation dispersion liquid, is provided. An optical information medium having a remarkably excellent anti-staining property of the surface which is on the incident side of recording/reproducing beam is provided. A method for evaluating an optical information medium, comprising: adhering an artificial fingerprint liquid containing a fine-particle-form substance and a dispersion medium capable of dispersing the fine-particle-form substance onto the surface of the optical information medium which is on the incident side of a recording/reproducing beam; observing the state of the artificial fingerprint liquid droplets adhered to the surface; and judging the quality of the medium surface.
