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： A light emitting device for focusing a laser beam without adopting an optical lens system is provided, as well as a composite magnetic recording head and a magnetic recording device, which realize a smaller laser spot diameter and a sharp magnetic field distribution, whereby an optical-assisted high density magnetic recording can be realized, and which also realize a simplified head structure, and improvements in productivity and costs. The composite magnetic recording head is prepared by integrally forming a magnetic coil layer for use in magnetic recording at around the center of the surface-emitting laser aperture, and further, a shielding plate is formed at the center of the laser aperture. As a result, a laser beam can be focused on the irradiation surface of the magnetic recording medium at portion right below the shielding member so as to locally heat the irradiated portion, and further a magnetic field for magnetic recording is applied in the laser heated portion, thereby realizing a high density magnetic recording.

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： An optical memory device for recording, reproducing, or erasing information applies an optical beam such as a laser beam onto a recording medium. The optical memory device includes a recorded region detecting circuit for detecting information recorded region formed in the recording medium. In the optical memory device, a timing control for recording, reproducing, or erasing is performed with the use of a result obtained through detection of a synchronizing signal, such as a sector mark, indicative of a starting point of an information block and another result obtained through detection in the recorded region detecting circuit. The recorded region detecting circuit includes either at least one peak hold circuit for detecting a peak level of the playback signal or a low pass filter for smoothing the playback signal, and a comparator for comparing an output obtained through the peak hold circuit or through the low pass filter with a reference voltage.
