摘要： In a recording apparatus for reproducing information recorded on a recording medium by utilizing near-field light, the recording apparatus realizes reliable information reproduction with a simple structure. Illumination light 20 is illuminated to the recording medium 10 to create near-field light on a surface of the recording medium 10. The created near-field light is scattered by a microscopic aperture 12 formed in the aperture element 11 so that scattering light (propagation light) thereof is detected to create a reproduced signal. Derived from the created reproduced light a distance control signal representative of a distance between the microscopic aperture 12 and the recording medium 10. Based on the distance control signal, the aperture element 11 is controlled in position. Due to this, the microscopic aperture 12 is brought into proximity to the recording medium 10.

摘要： In an information recording apparatus for recording information onto a recording medium by utilizing a technology in a near-field microscope, the information recording apparatus carries out recording with reliability and density. An optical probe (1) or micro-cantilever (12) utilized in a near-field microscope is used as a recording probe (26). The recording probe (26) at its tip is heated by laser light (28) illumination or heating by an electric heating element to radiate microscopic-region thermal energy through the tip to a recording medium (3). This makes it possible to record microscopically information onto the recording medium (3) that varies in physical properties due to heating. Furthermore, thermal energy is provided to a recording position through an auxiliary heat radiating means thereby enabling recording more positively.

摘要： An optical switch has at least first, second, and third optical fibers disposed generally parallel to each other and spaced at non-equal intervals in a direction substantially perpendicular to an optical axis of each of the optical fibers. The optical fibers have tip portions disposed approximately along a straight line extending in a direction substantially perpendicular to the optical axis of each of the optical fibers. A first non-movable guiding structure guides a beam of light emitted from the first optical fiber to the second optical fiber along a first optical path disposed between the tip portion of the first optical fiber and the tip portion of the second optical fiber. A second movable guiding structure guides the beam emitted from the first optical fiber to the third optical fiber along a second optical path disposed between the tip portion of the first optical fiber and the tip portion of the third optical fiber so that a length of the second optical path is substantially equal to a length of the first optical path.

摘要： The present invention has an object, in a near-field optical probe having a microscopic aperture to generate and/or scatter a near field, to obtain a near-field optical probe easy to be made in an array which increases the intensity of a near field to be generated and/or scattered and is adapted for use as an optical memory head. This near-field optical probe is arranged with a planar lens having microscopic lens on a flat surface substrate having an inverted conical or pyramidal hole formed therethrough such that its apex is made as the microscopic aperture, wherein a light source is further arranged thereon to introduce light to the planar lens. Because the arrangement is made such that the planar lens has a focal point positioned at the microscopic aperture, the light given by the light source can be efficiently collected to the microscopic aperture. Also, the above structure can be arrayed and mass produced using a silicon process, thus being adapted for use as an optical memory head.

A metal particulate is dispersed only in the data mark arrangement layer so that a surface plasma is generated upon interaction of the data mark arrangement layer with near field light generated by incident light or irradiating light to thereby amplify the intensity of scattered light generated as a result of the interaction between the data mark arrangement layer and the near field light.
