摘要： A thermally-assisted recording (TAR) head for recording data in data tracks of a TAR disk has an air-bearing slider that supports a near-field transducer (NFT) and an optical waveguide that directs laser light to the NFT. The NFT has an output end at the slider's air-bearing surface (ABS) located between the write pole and the optical waveguide in the along-the-track direction. The NFT output end is generally triangularly shaped with an apex facing the write pole and a back edge wider than the apex in the cross-track axis direction facing the waveguide. The surface of the waveguide facing the NFT back edge is tapered, with a width in the cross-track axis direction at a region recessed from the ABS and a smaller width in the cross-track axis direction at an end near the ABS.

摘要： A determination oxygen storage amount used to determine whether a catalyst is degraded is a value obtained by applying a correction amount for removing error caused by response delay time of an output signal of an oxygen sensor to an oxygen storage amount calculated every short time. The correction amount is a value that is calculated using slopes stored in memory, i.e., the slopes for the number of storage cycles (>the short time) corresponding to the response delay time, or the like, and becomes more accurate as a value corresponding to the error as the storage cycle becomes relatively shorter with respect to the response delay time and the number of the slopes stored in the memory increases. The necessary storage capacity of the memory is inhibited from increasing excessively even if the number of the slopes stored in the memory is large.

摘要： In a head for thermal assisted magnetic recording device, a semiconductor laser is mounted so that the total height of the head does not become larger and light power fluctuation due to wavelength fluctuation occurs less frequently. In addition, the rise in temperature of the mounted semiconductor laser is suppressed. A semiconductor laser is placed on a side surface which is different from surfaces on an inflow end side and a trailing side, of four side surfaces of a floating slider. An entrance of a waveguide is placed on the side surface of the floating slider, to thereby cause emitted light from the semiconductor laser to directly enter the waveguide. A curved line part or a reflective mirror is formed in the middle of the waveguide so that the light which has entered the waveguide travels toward an optical near-field generating element.

摘要： A thermally assisted magnetic recording head with highly efficient optical coupling, while guiding a laser beam from a semiconductor laser element, i.e., a light source, to a leading end thereof, eliminating an influence due to heat generated by the element, and having excellent floating characteristics. The thermally assisted magnetic recording head includes a substrate 2 having a first optical waveguide 1, a semiconductor laser element 100, and a slider 4 having a second optical waveguide 3 formed on an end surface. The semiconductor laser element 100 is fixed on the substrate 2 so that light emitted from the element 100 propagates through the first optical waveguide 1, and a slider 4 is fixed on the substrate 2 so that light emitted from the first optical waveguide 1 propagates through the second optical waveguide 3. High optical coupling efficiency is then achieved, while ensuring both heat-dissipating and floating characteristics.

摘要： A near-field optical probe and optical near-field generator are provided. A problem of a probe having a scatterer in which optical near-field noises are generated at the parts other than for a point at which an intense optical near-field is generated, is solved. In one example of the probe, a surface of the parts except for a vertex of the scatterer at which the intense optical near-field is generated is etched so that an etching depth becomes not less than a penetration depth of the optical near-field. The probe facilitates control of noises when a sample is observed or recording marks are reproduced.
