摘要： High density data storage device has a support substrate and one or more different types of phosphors contained at each of plural regularly arranged microscopic regions of the support substrate. Each of the different types of phosphors has a fluorescence characteristic that may be faded by incident light having a different predetermined wavelength. The use of near-field light facilitates a reduction in size of the space required for each data bit. By providing a plurality of different types of phosphors at each of the microscopic regions, the amount of information storable at each bit space is rendered multi-valued to enable higher density recording.

摘要： An optical microcantilever for a scanning near field microscope comprises a support section, a cantilever-shaped optical waveguide, and a light blocking wall. The optical waveguide has a free end, a fixed end fixed to the support section and terminating in a light input/output end, and a tip formed at a side of the free end of the cantilever and having a microscopic aperture at an end thereof. The light blocking wall blocks the transmission of light scattered from a region of the light input/output end in the direction of the tip of the optical waveguide.

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.

摘要： A near-field optical head has a minute structure formed in the support member for interacting with a recording medium via near-field light. An optical waveguide is provided on the support member for guiding light between a light source and the minute structure. The optical waveguide has a core, a clad and a reflective surface, the core having an end face facing the reflective surface and being spaced therefrom so that light traveling through the optical waveguide is projected from the end face of the core onto the reflective surface and is reflected by the reflective surface toward the minute structure. Information is recorded to and/or read from the recording medium based on the scattering of near-field light between the recording medium and the minute structure while the near-field optical head is positioned over the surface of the recording medium.

摘要： It is an optical information recording and reading apparatus for recording and/or reading information at a high density by using a near-field light-generating device as a near-field optical head. The end surface of the core of a flexible optical waveguide is formed in an intermediate position in the optical waveguide and in a portion fixed to the near-field optical head. Light for recording and reading information is spread within the clad. The spread light flux is reflected toward the near-field optical head by a reflective surface formed on the side of one end of the optical waveguide. The reflected light flux is collected by light-collecting structures and then is made to enter an optical minute aperture formed in the near-field optical head. Near-field light is created near the minute aperture. Light scattered by the surface of the recording medium is received. Thus, information on the recording medium can be recorded and read.

摘要： A near-field optical head capable of rapid recording and/or reproducing of the information is provided. The near-field optical head condenses the light from the light source and irradiates the light on the minute opening 1. Then, by means of detecting the reflected light from the light condensing mark 501 provided on the circumference of the minute opening 1, the relative position between the light condensing point condensed by the lens and the light condensing mark 501 is detected so that the light condensing point is controlled to follow the light condensing mark 501. Thus, intensive and constant near-field light can be generated in the minute opening 1 and a signal having high S/N can be obtained even by a rapid scanning of the minute opening 1 over the recording medium so that rapid recording and/or reproducing of the information is made possible.
