    摘要： A testing method capable of quantifying abrasion resistance on the translucent base surface of a high-recording-density optical information medium simply and in a form of reflecting an actual application environment, and judging criteria appropriate for the testing method. When an evaluation test in terms of abrasion resistance on a laser beam incident-side surface is conducted on an optical information medium to and/or from which recording and/or reproducing is made by a laser beam shone into an information recording layer from a translucent base side, and which has the focused radius R, of a recording/reproducing laser beam on the translucent base surface, of 40-400 μm, defined by the following expression (1) R=2T tan [sin−1 (NA/n)](1) (in the expression, T is the thickness (μm) of the translucent base, NA numerical aperture of an object lens in the recording/reproducing device, and n refractive index of the translucent base), the abrasion resistance on a laser beam incident-side surface is evaluated based on the error amount of a reproduction signal after a laser beam incident-side surface is abraded by an abrasion wheel specified in ISO9352.
