摘要： An optical microcantilever for a scanning near field microscope has an optical waveguide for propagating light. The optical waveguide has a longitudinal axis, a light input/output end, a free end opposite to the light input/output end, and a tip formed at the free end of the cantilever and having a microscopic aperture at an end thereof. A support section has a first portion supporting the optical waveguide, a second portion and a third portion. The second portion has an optical element guide channel formed in the support section for supporting an optical element acting on light entering the optical waveguide or on light exiting from the optical waveguide and for determining a position of the optical element. The third portion is disposed between the first portion and the second portion and has a surface disposed at an angle of inclination relative to the longitudinal axis of the optical waveguide. The light input/output end of the optical waveguide projects above the third portion for reducing a coupling loss between the optical element and the optical waveguide.

摘要： There is disclosed a near-field optical head having an microscopic aperture whose size can be varied. The optical head comprises a substrate of silicon. A hole in the form of an inverted cone is formed in the substrate. The top portion of this hole forms the microscopic aperture. A support portion for supporting an actuator is formed on the substrate. The actuator holds a light-blocking film in such a way that the light-blocking film stays in the hole and that the bottom surface of the light-blocking film is flush with the bottom surface of the microscopic aperture. The light-blocking film is moved by the actuator to change the aperture to desired size.

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： A near-field optical head which reproduces, with high S/N, information recorded with extreme density and is compact in structure. On an electrode (2) is formed a recording medium (3) that emits a light by applying an electric field. Brought into proximity to a recording medium (3) is a near-field optical head (101) having a slider (31) formed with an inverted cone formed hole such that an apex thereof is rendered as a microscopic aperture (6). A microscopic electrode (5) is formed on a side surface (32) of the inverted cone formed hole. An electric field (9) is applied only to a microscopic region to cause light emission. It is possible at the aperture (6) to detect a light emitted only by the microscopic region.

摘要： A near-field optical head applied for a head of an information recording/reading apparatus for realizing information recording and reading with high density recording medium at high speed and with reliability through interaction between a near-field light and a recording medium using a slider having a near-field optical probe. A slider (1) having a near-field optical probe is put into proximity to a recording medium (3). Further, a distance is reduced between a light emitting element (2) and a microscopic aperture (7). The microscopic aperture is controlled in protrusion amount from the recording medium (3) by a piezoelectric element. Due to this, the light intensity in the probe or light detecting section is increased to increase interaction with the recording medium (3). This realizes information recording and reading apparatus with high sensitivity and accuracy.
