    Abstract: For irradiating a layer a radiation beam is directed and focussed to a spot on the layer, relative movement of the layer relative to the optical element is caused so that, successively, different portions of the layer are irradiated and an interspace between a surface of the optical element nearest to the layer is maintained. Furthermore, at least a portion of the interspace through which the radiation irradiates the spot on the layer is maintained filled with a liquid, the liquid being supplied via a supply conduit and flowing out of an outflow opening through a total projected cross-sectional passage area in a plane parallel to the layer. The outflow opening or a plurality of the outflow openings are positioned such that, seen in a direction perpendicular to the layer, the total cross-sectional area has a centre in the portion of the interspace through which the radiation irradiates the spot.

    Abstract: An optical disk device has a semiconductor laser (21) that oscillates in a multiple mode, a first polarization-preserving fiber (33), and a second polarization-preserving fiber (36). The first and second polarization-preserving fibers (33, 36) form an optical path through which the laser beam emitted from the semiconductor laser (21) is transmitted so as to compensate for the variation of polarization caused while the laser beam travels through one of the polarization-preserving fibers by means of the other. As a result, the laser beam in multiple mode can travel through the optical fibers while maintaining the polarization of the laser beam.

    Abstract: A near-field optical system having one or more solid state lasers and an aerodynamically shaped slider which comprise a single integrated, monolithic device fabricated from the same base semiconductor material. The monolithic optical head can be quickly and easily attached to the read arm of an optical read/write device without requiring attachment of separate laser elements, and without micropositioning or use of optical microscopy for positioning the lasers. The optical head comprising a single semiconductor substrate including a first region which defines a slider having an air bearing surface, and at least one second, laser region which defines a diode laser, with the diode laser having an emission face which is substantially co-planar with the air bearing surface. The semiconductor substrate preferably includes an active layer, a p-clad layer or reflective layer adjacent a first side of the active region, an n-clad layer or reflective layer adjacent a second side of the active layer, and an n-semiconductor layer adjacent the n-clad layer. A slider region of the semiconductor substrate includes an air bearing surface, adjacent the p-clad layer, which is aerodynamically structured and configured to define a slider. The integral lasers include a p-electrical contact adjacent to the p-clad layer and proximate to the laser emission face, and an n-electrical contact adjacent to the n-clad layer or an n-semiconductor layer. The laser mode is defined by oxidized or ion-diffusion regions associated with the p-clad layer or n-clad layer of the laser. A conductive via through the substrate allows electrical connection with the p-side contact to be achieved from the n-side of the substrate. The optical head is used in a near-field optical system with an optical medium having a phase change layer.

    Abstract: An optical record and reproduce head records and reproduces information with high reliability using an optical interaction in a minute area with high-density media rotating at high speed. An optical waveguide acts to apply load to a slider (6) that receives a lift, e.g., the same system introduces light to the slider (6) and apply load to the slider (6). As a result, stabilized attitude control of the slider (6) and an increase in light intensity on the media allows recording and reproducing information with high reliability. Further, a microstructure is arranged on the edge of the slider (6) facing the media to decrease the distance to the media, thereby achieving high-density recording of information.
