摘要： 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. For example, the quality of the medium surface is judged by: (1) Measurement of the area ratio of the surface occupied with the artificial fingerprint liquid droplets adhered per unit area of the surface; (2) Measurement of the diameter of the artificial fingerprint liquid droplets adhered to the surface; (3) Measurement of the number of the artificial fingerprint liquid droplets adhered per unit area of the surface; or (4) Measurement of the degree of roundness of the artificial fingerprint liquid droplets adhered to the surface.

摘要： An object is to stick an artificial fingerprint liquid on a test sample in a constant condition. An artificial fingerprint stamping apparatus 1 operates such that as an arm 10 lowers, the self weight of a stamp unit 3 causes an artificial fingerprint transfer member 9 at the lower end of a stamp pin 6 attached to the arm 10 via a ball bush 11 to be pressed against an artificial fingerprint liquid transfer disk D1 for a predefined period of time, and thus an artificial fingerprint liquid is transferred onto the lower end surface of the artificial fingerprint transfer member 9. Then, after the artificial fingerprint transfer member 9 is positioned above a test disc D1, the arm 10 is lowered so that the self weight of the stamp unit 3 causes the artificial fingerprint transfer member 9 to be pressed against the test disc D1 for a predefined period of time.
