摘要： An optical recording medium has a recording layer formed of a plurality of reflection hologram layers. A spacer layer is interposed between the respective reflection hologram layers. The reflection hologram layer is made of a material having a thermal threshold value which allows, when being irradiated with a recording laser beam, local absorbed heat to vary hologram diffraction conditions at a focal position, and allows the hologram to be retained at non-focal positions. The spacer layer is made of a material which is insensitive to a laser beam of a recording wavelength and which has a smaller extinction coefficient than that of the reflection hologram layer.

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.

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.
