Abstract: An optical data storage system writes or reads information with respect to an optical storage medium using an optical pickup including a solid immersion optical system or a solid immersion lens for generating a near-field and emitting a light beam. The optical storage medium includes a recording layer which is formed on a surface of an optical transmissive layer opposite to another surface of the optical transmissive layer which opposes the solid immersion optical system or solid immersion lens. The thickness of the optical transmissive layer is larger than one wavelength of the light beam. The interval between the surfaces of the solid immersion lens or solid immersion optical system and the optical transmissive layer is smaller than one wavelength of the light beam. Thus, the light beam reflected from the inside of an air gap and the inside of the optical storage medium between the air gap and the recording layer does not function as noise with respect to the light reflected from the recording layer. Also, since the thickness of a protective layer or a substrate which is an external surface of the optical storage medium can be thickened, information can be written or read with respect to the optical storage medium even when the optical storage medium has dust and/or damage.

Abstract: An optical data storage system includes a light emitting and receiving device (30), a light transmission device (31) having an input port (32) and an output port (33). The input port is disposed adjacent to the light emitting and receiving device. Furthermore, a micro window is provided at the output port, and a diameter of the micro window is in a range of 5 to 70 nanometers. Therefore, in the optical data storage system, the spot size of the light beams is close to the diameter of the micro window. Accordingly, the size of the beam spot is small enough to write information at a higher density with respect to an optical storage medium.

Abstract: A data writing system includes an array of cells for storing data and a write transducer that moves over a selected cell in the array of cells. The write transducer includes a writer producing a write magnetic field that intersects the selected cell. The write transducer also includes a plasmon resonator that is adjacent the writer. The plasmon resonator is shaped to receive lower power density radiation and to provide plasmon radiation at a higher power density to an optical spot intersecting with the selected cell. The plasmon radiation heats the selected cell above a write temperature.

Abstract: Disclosed are a cantilever-type near-field probe capable of easily improving an optical throughput and being applied to a head of an optical data storage and a method of manufacturing the same. An oxide film is formed on a silicon substrate having dielectric films formed as a mask layer on upper and lower portions thereof, and a circular dielectric film formed on the upper mask layer and providing a function of a holder. A distal end of the probe has a parabolic structure by use of an effect of a bird's peak provided due to a difference of growth rate of the oxide film produced by the dielectric film, thereby forming the initial probe. After the dielectric film is removed from the initial probe, a bottom surface of the silicon substrate is removed, thereby providing the probe with the near-field aperture having a high throughput.

Abstract: Electromagnetic radiation from an optical source is directed onto an optical aperture in a metallic structure. The metallic structure in turn emits optical output from an emission region in the structure and onto a recording medium (e.g., a magnetic recording disk), thereby heating the medium. The optical output is enhanced when the electromagnetic radiation from the optical source includes a frequency that matches a waveguide mode resonance in the metallic structure. Features (such as ridges or trenches) in the metallic structure may be used to further increase the emitted optical output beyond what the emitted optical output would be in the absence of these features. The apparatus and associated method are useful for data recording, e.g., thermally assisted data recording.

Abstract: An aperture 12 for producing an evanescent wave is provided at an n-Au electrode 106. The aperture 12 is directed roughly perpendicularly to a direction in which end faces 104a of an active layer 104 of an optical device oppose to each other, and therefore, laser light generated in the active layer 104 is made incident in the form of the p-polarized light. By the incidence of the p-polarized laser light, an evanescent wave of a comparatively great intensity is obtained from the aperture 12. With this arrangement, an optical device capable of obtaining an evanescent wave of a comparatively great intensity is provided.
