摘要： A magnetic sensing section is constituted by a magneto-resistive device in which a fixed magnetization layer, a non-magnetic layer, and a magnetization-free layer are deposited in that order on a first buffer layer that is deposited on a magnetic layer. A second buffer layer sandwiches the magnetic sensing section, and a biasing layer which covers right and left sides of the magnetic sensing section. The second buffer layer is deposited on the magnetic layer with a nonconductor layer interposed therebetween. A near field light generation section constituted by a second magnetic layer, a dielectric layer, and a metal layer is formed on a surface of the second buffer layer not adjacent to the nonconductor layer. The resultant magnetic sensor device can efficiently perform photo-assisted reproduction of information from a magnetic recording medium using a magnetic reproduction head or a magnetic reproducer.

摘要： An electromagnetic field detecting element 10 includes a lamination of three insulation layers 2, 3, and 4. The dielectric breakdown strength of the insulation layer 3 is greater than the dielectric breakdown strengths of insulation layers 2 and 4. The three insulation layers 2, 3, and 4 are disposed between a pair of electrodes 5 and 6. Boundaries 7 and 8 on both ends of an overlapping region of the opposing surfaces 5a and 6a in a Z direction are apart from the insulation layer 3 by thicknesses t1 and t3 of the insulation layers 2 and 4, respectively. Between the pair of electrodes 5 and 6, ballistic current paths interposing therebetween the insulation layer 3 are formed by applying, between the pair of electrodes 5 and 6, an electric field having a magnitude which causes dielectric breakdown in the insulation layers 2 and 4 while causing no dielectric breakdown in the insulation layer 3. Thus, it is possible to perform at a room temperature a highly efficient electromagnetic field detection utilizing AB effect or AC effect.

摘要： A magnetic read/write head includes: a slider having an ABS, a surface at an leading edge, and a surface at an trailing edge; a piezoelectric device arranged on the surface at the trailing edge of the slider; and a magnetic read/write element arranged on the piezoelectric device. The piezoelectric device, upon application of voltage, is displaced asymmetrically with respect to a displacement axis which is on the surface at the trailing edge of the slider and which is perpendicular to the surface of the magnetic recording medium. With this asymmetrical displacement of the piezoelectric device, the magnetic read/write element rotates about the rotation axis perpendicular to the surface of the magnetic recording medium.

摘要： 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.

摘要： An electromagnetic field generating element restrains magnetic field attenuation or magnetic field delay in a high frequency recording/reproducing head for thermally assisted magnetic field recording/reproduction using a near field. An information recording/reproducing head and an information recording/reproducing apparatus carry out high frequency magnetic recording/reproduction. The electromagnetic field generating element includes: (i) a substrate, (ii) conductors each provided on the substrate and each serving as a supporting section, (iii) a plate-like-shaped conductor provided on the conductors and (iv) a semiconductor laser element provided on the substrate. The semiconductor laser element irradiates laser light to the plate-like-shaped conductor substantially parallel to an extending flat surface of the plate-like-shaped conductor. This causes generation of a near field in the plate-like-shaped conductor. In addition, a magnetic field is generated by supplying a current to the plate-like-shaped conductor.
