    • A method of manufacturing a multilayered recording medium. A transmissive stamper with a depression protrusion contour contacts a protection layer on a supporting base. The transmissive stamper is then irradiated with ultraviolet rays to cure the protection layer and the transmissive stamper is subsequently removed. A recording layer is deposited on the cured protection layer. Further, another recording layer is deposited on the transmissive stamper. Next, an intermediate layer is formed on the recording layer deposited on the transmissive stamper and thereafter, the intermediate layer is attached to the recording layer on the cured protection layer. Then, the transmissive stamper is irradiated with ultraviolet rays to cure the intermediate layer. Thereafter, the supporting base is removed from the protection layer. These steps produce a multilayered optical recording medium.
    • 一种多层记录介质的制造方法。 具有凹陷突起轮廓的透射式压模与支撑基座上的保护层接触。 然后用紫外线照射透射式压模以固化保护层,随后去除透射式压模。 记录层沉积在固化保护层上。 此外,另一记录层沉积在透射式压模上。 接着,在沉积在透射型压模上的记录层上形成中间层,然后将中间层附着在固化保护层上的记录层上。 然后,用紫外线照射透射式压模以固化中间层。 此后,从保护层移除支撑基底。 这些步骤产生多层光学记录介质。

    • A magneto-optic recording medium in which information is reproduced while a recording magnetic domain is enlarged by displacing a domain wall based on a temperature distribution formed by a beam of light and having a maximum temperature Tr. The recording medium comprises a reproducing layer in which a domain wall is displaced, a recording layer for holding a recording magnetic domain corresponding to information, and a cutoff layer disposed between the reproducing layer and the recording layer and having a Curie temperature lower than those of the reproducing layer and recording layer. The recording medium satisfies the following condition; (Tr−RT)/(Tc2−RT)≧1.8 where Tc2: Curie temperature of the cutoff layer, and RT: room temperature.

    • In an optical information recording/reproducing apparatus, while a magnetooptical recording medium formed by stacking at least a recording layer, which consists of a perpendicular magnetization film for magnetically holding information, and a reproducing layer is rotated at a fixed angular velocity, a laser beam is applied to the medium from the reproducing layer thereby reproducing information held by the recording layer by transferring the information to the reproducing layer. First, information which indicates a relation of an optimum intensity of the laser beam in reproduction with respect to a radial position on the recording medium, previously recorded on the recording medium, is reproduced. Then, the intensity of the laser beam is adjusted on the basis of the information indicating the relation of the optimum intensity of the laser beam with respect to the radial position on the recording medium.
