摘要： An optical switching system is disclosed which can achieve high-speed optical switching with a simple configuration. Light from a light irradiation section is irradiated into an optical transmission line made of a material having a non-linear optical effect and disposed on the upstream side with respect to an optical switch provided for performing switching of a transmission line to cause the non-linear optical effect to occur. Thereupon, light is emitted externally from the optical transmission line by the non-linear optical effect between the light irradiated by the light irradiation section and light propagating in the optical transmission line. The light emitted is received by a light reception section to acquire intensity information of the light propagating in the optical transmission line. The intensity information is used as a driving signal for driving the optical switch.

摘要： An optical device used for converging a light beam on a signal recording surface of an optical disc includes an optical lens for converging the light beam on a signal recording surface of the optical disc and a light barrier portion provided on a surface of the optical lens facing the optical disc. The light barrier portion includes a light transmitting aperture through which is transmitted the light beam converged by the optical lens. The light beam illuminated on the optical disc has its diameter controlled by this light transmitting aperture. The light radiated by a light source so as to be incident to the optical device is converged by the optical lens. The light converged by the optical lens is transmitted through the light transmitting aperture and illuminated on the signal recording surface of the optical disc. The diameter of the light beam illuminated on the signal recording surface of the optical disc is controlled by the light transmitting aperture, and thus the numerical aperture NA of the optical device is determined.

摘要： An optical lens whose focal length is different on first and second planes perpendicular to each other is provided. The optical lens is configured such that a convex element, which is formed integrally with a substrate having a flat face, has a convex curved face that functions as an optical lens and is shaped such that the curvature on a first cross section and the curvature on a second cross section perpendicular to and intersecting with the first cross section are different from each other, whereby the focal lengths on the first and second cross sections are different from each other. A groove of a substantially elliptical shape or a substantially rectangular shape is formed along the boundary between the substrate and the convex element. The optical lens is used to produce a focus error signal or is incorporated into an optical pickup apparatus.

摘要： In a recording medium manufacturing method for obtaining a recording medium by effecting a surface smoothing treatment on a surface smoothing treatment surface of a surface of a medium, the surface smoothing treatment surface of the medium is locally pressed by a polishing work tape having a pressure area less than 1 mm, more preferably, less than 0.5 mm with respect to both radial direction and tangential direction relative to rotation of the medium. In a polishing work of recording medium manufacturing process, a problem of occurrence of defects such as scratches on the surface layer can be improved, whereby yield can be increased and mass-productivity can be improved.
