摘要： An optical waveguide probe is disclosed which is used for a scanning near-field optical microscope, has a low light propagation loss, and is capable of performing an AFM operation, and a manufacturing method thereof is disclosed. The vicinity of the tip of an optical waveguide 2 is bent toward a side of a probe portion 9 through a plurality of surfaces symmetrical with respect to a plane including an optical axis of the optical waveguide 2. By this, a loss of a propagated light 7 at a bent portion 10 is reduced, and the propagated light 7 can be condensed to a minute aperture 5, so that near-field light can be efficiently emitted from the minute aperture 5.

摘要： An optical head for optical recording/reading apparatus, which records and reads information with high reliability, by making use of an optical interaction with a medium in a minute area, on a high density medium revolving at high speed. It has a structure, in which an optical waveguide mechanism applies a loading force to a slider 6 receiving a buoyant force, and a system for introducing a light to the slider 6 and a system for applying the loading force are integrated into an identical body. As the result, a stable posture regulation of the slider 6 and an increase of the light intensity of irradiation on the medium can be achieved, and it becomes possible to record and read information with high reliability. Furthermore, by disposing a minute structure in the vicinity of an edge in the surface facing the medium of the slider 6, so that the minute structure can come closer to the medium, further improvement in high density can be made.

摘要： A recording medium and near-field optical probe utilizing near-field light to achieve high density of information recording and hence enhance resolution in reproducing. A phase shift arrangement layer is formed arranged alternately with a phase shifter region to cause shift by 180 degrees in incident light and a transmission region transparent for a wavelength of the incident light. Furthermore, a row of data marks are arranged in a position above the phase shifter regions and transmission region. Due to this, cancellation is made between spread of near-field light due to incident light transmitted through the phase shifter region and spread of near-field light due to incident light transmitted through the transmission region, providing sharpness in an intensity distribution of near-field light over the data mark. Also, a phase shifter is provided at a through-hole of the near-field optical probe, enabling to produce more localized near-field light.

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.
