摘要： An information reproducing apparatus has a medium with a linear tracking mark extending in a scanning direction and a linear data mark extending in a direction orthogonal to the scanning direction. A light control unit irradiates the data mark with a first near-field light polarized in the scanning direction and irradiates the tracking mark with a second near-field light polarized in the direction orthogonal to the scanning direction. A detector detects light scattered by the data mark and the tracking mark irradiated with the first near-field light and the second near-field light, respectively. A signal processing unit processes a first output signal from the detector corresponding to the detected light scattered by the data mark and processes a second output signal from the detector corresponding to the detected light scattered by the tracking mark. The signal processing unit has a control circuit that carries out tracking control in accordance with an intensity of the second output signal and that carries out access control in accordance with an intensity of the first output signal.

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： 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： 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.
