    摘要： The present invention provides a compact optical isolator. A polarizer 2A and/or an analyzer 2B of an optical isolator 1 are/is formed of a cobalt magnetic substance minute particle cluster thin film 2. The cobalt magnetic substance minute particle cluster thin film 2 can be formed in the form of tape, film or sheet, whereby the thickness of the polarizer 2A and/or the analyzer 2B can be made small and in addition thereto, the polarizer and/or the analyzer can be formed integrally with a magneto-optical member which is formed in the form of thin film. More compact dimension and lighter weight can be realized as compared with the prior art in which Rochon prism made of calcite, rutile single crystal having wedge form or polarizing beam splitter is employed as the polarizer and the analyzer.

    摘要： An object of the present invention is to make it possible to record information on an optical information recording medium in the form of three dimensional interference patterns so that the information is erasable in part.The optical information recording medium (1) has an information recording layer (3) made of a magneto-optic recording material. A pick-up (11) of an optical information recording/reproducing apparatus generates information light by spatially modulating laser light emitted from a light source unit (20) with a spatial light modulator (22), and generates recording-specific reference light spatially modulated in phase by spatially modulating the phase of the laser light emitted from the light source (20) with a phase-spatial light modulator (16). The information recording layer (3) of the optical information recording medium (1) is irradiated with the information light and the recording-specific reference light. An electromagnetic coil (30) applies a magnetic field to the information recording layer (3). A three-dimensional distribution pattern of magnetization corresponding to the interference pattern resulting from the information light and the recording-specific reference light is formed in the information recording layer (3).
