    摘要: The present invention provides a low-cost artificial fingerprint liquid for quantitatively and with a good reproducibility evaluating an anti-staining property, and a fingerprint adhering property or a fingerprint removing property on the surface of an optical disk such as a reproduction-only optical disk, optical recording disk, magneto-optical recording disk, various displays such as a CRT, and various substances such as glass. An artificial fingerprint liquid comprising a fine-particle-form substance and a dispersion medium capable of dispersing the fine-particle-form substance. The dispersion medium preferably has a surface tension ranging from 20 to 50 mN/m at 25° C., and preferably is selected from at least one of higher fatty acid, derivative of higher fatty acid, terpens, and derivatives of terpens. The fine-particle-form substance is at least one selected from inorganic fine particles and organic fine particles. The present invention provides a testing method for an optical information medium using the artificial fingerprint. The present invention provides an optical information medium which is good in the property of wiping off an organic stain, such as a fingerprint, adhering to a surface of the optical recording medium and which can maintain good recording/reproducing property over a long period.

    摘要: An optical information medium comprising a supporting substrate, an information recording area on the supporting substrate, and a light-transmitting layer covering at least the information recording area, wherein the information recording area is irradiated with the recording/reading laser beam through the light-transmitting layer, and wherein the light-transmitting layer is highly scratch resistant upon contact with the optical pickup is provided. Also provided is an optical information medium which has a scratch-resistant light transmitting layer, and which experiences reduced vibration in high-speed rotation without suffering from problems in focus servo and tracking servo. In such optical information medium, the surface of the medium on the side of the laser beam incidence at least in the part above the information recording area has a dynamic coefficient of friction of up to 0.4.
