摘要： A fine particle dispersion composition comprises metal-oxide fine particles; an organic resin material adapted to cure by absorbing energy; one of polyoxyethylene alkyl ether phosphoric acid-based surfactant and a polyoxyethylene alkyl ether carboxylic acid-based surfactant (each having molecular weight of >= 500); and an organic solvent. The composition becomes an optical component when cured. Independent claims are included for the following: (1) an optical film laminate having several stacked optical films that differ in refractive index from one another. The optical film is obtained by curing the fine particle dispersion; (2) a polarization splitting device having a transparent base member having inclined plane surfaces formed in it by grooving, the inclined plane surfaces differing in inclination direction from each other. The inclined plane surfaces has a polarization splitting multilayer film formed on it. The transparent base member and/or the polarization splitting multilayer film is obtained by curing the fine particle dispersion composition; and (3) preparation of optical component involving performing dispersion treatment on metal-oxide fine particles, an organic resin material adapted to cure by absorbing energy; one of polyoxyethylene alkyl ether phosphoric acid-based surfactant and a polyoxyethylene alkyl ether carboxylic acid-based surfactant (each having molecular weight of >=500) in organic solvent together with high hardness metallic balls or ceramic balls; subsequently applying dispersion solution and evaporating the organic solvent.

摘要： PROBLEM TO BE SOLVED: To provide a hologram recording medium in which a sealing portion of high reliability is easily and inexpensively provided on a recording layer in the outer rim of a hologram recording medium and to provide a method for manufacturing the medium. SOLUTION: The method for manufacturing a hologram recording medium includes a step of forming a sealing portion by forming a recording layer 2 comprising a photosetting organic material that contains monomers, a hardening initiator and a sensitized dye on a transparent substrate 1, exposing the recording layer corresponding to the outer rim of the hologram recording medium to light L E at a photosensitive wavelength to harden the photosetting organic material so as to seal the photosetting organic material in a region inside the outer rim. The step of forming the sealing portion is carried out by exposing the recording layer while measuring the transmittance for the exposure light L E in the recording layer and then terminating the exposure when the transmittance measured reaches the transmittance or more corresponding to the end point of the hardening reaction of the photosetting organic material.

摘要： PURPOSE:To obtain an accurate focusing error signal without enlarging and complicating constitution by reading an information signal with a difference of transition quantity between the direction of polarization of an incident light and that of a reflected light. CONSTITUTION:A linear polarization luminous flux of a light source 1 makes a focusing point 9 on a recording groove 12 through a beam splitter 2 and an object lens 3. The direction of polarization of an incident luminous flux is parallel to or orthogonal to the groove 12, and it prevents degradation of a reproduced signal caused by double refraction of a disk substrate. A reflected luminous flux at the focusing point 9 is slightly rotated with the direction of polarization of the incident luminous flux as a reference, reflected by the beam splitter 2, enters a cylindrical lens 4, and causes astigmatism in the direction in accordance with the generatrix direction. A light beam is received by detectors 6, 7 in accordance with variation quantity in the direction of poralization by the beam splitter 5, an operation circuit 18 obtains information reading and focusing error signals from outputted light of four light receiving sections, and a driving circuit 19 supplies a current to an actuator coil 20. By using this constitution, offset is not caused in a focusing error signal even if double refraction is caused in a perpendicular direction in the substrate.

摘要： PROBLEM TO BE SOLVED: To provide an optical information recording medium that can increase the recording speed. SOLUTION: The optical information recording medium includes a recording layer 121 that has a recording area 121a on which a cavity is formed as a recording mark RM as a result of an increase in temperature around a focal point after absorbing a recording beam L2c converged for recording of information and having a predetermined energy value in accordance with the wavelength of the recording beam L2c and from which, when a predetermined reading beam L2d is emitted for reproducing of the information, the information is reproduced based on an optically modulated returned beam L3. Further, the recording layer 121 has a non-recording area 121b which is provided adjacent to the recording area 121a and on which the recording mark RM is not formed when the recording beam L2c is radiated.
