    摘要： A magnetic recording device is provided according to the present invention for magnetic recording on a recording medium. The magnetic recording device includes a magnetic pole and a C-aperture structure disposed adjacent the magnetic pole. A focusing element receives light from a light source and focuses the received light onto the C-aperture structure, such that the light incident upon the C-aperture structure and a magnetic flux flowing through the magnetic pole are co-locatable on a recording medium disposed adjacent to the magnetic recording device. The focusing element may include a planar waveguide receiving and focusing the light onto the C-aperture structure.

    摘要： A magnetic recording head consists of a write pole and a near field transducer close to the write pole that focuses light energy to a focal point. A near field transducer is positioned to receive light energy from a waveguide. The near field transducer comprises an energy-receiving end and an energy-radiating end. The energy-receiving end is located near the focal point of the waveguide and the energy-radiating end is shaped such that it is narrower closer to the write pole and wider farther from the write pole.

    摘要： An optical assaying method and system having a movable sensor is described. In one aspect, the present invention is a sensing system having a rotating sensor disk coated with indicator dyes sensitized to a variety of substances. In this configuration the sensing system further includes a detector for sensing spectral changes in light received from one or more of the indicator dyes. In another aspect, the present invention is a sensing system having a surface plasmon resonance sensor disk having grooves extending radially from a center of the disk. In yet another aspect, the present invention is a sensing system including a diffraction anomaly sensor disk having a dielectric layer that varies in thickness. The present invention allows for construction of an inexpensive sensing system that is capable of easily detecting a variety of substances either in a sample or a surrounding environment. Furthermore, the present invention provides a sensing system capable of sensing multiple substances without requiring multiple sensors.

    摘要： A heat assisted magnetic recording head having a planar waveguide for heating a recording medium proximate to where a write pole of the recording head applies a magnetic write field thereto. The planar waveguide includes at least one edge, which may have a substantially parabolic shape, that is shaped to reflect an electromagnetic wave to a focal point within the planar waveguide. The planar waveguide includes a truncated end adjacent the focal point such that the truncated end intersects the focal point.
