摘要： A giant magnetoresistance-dual magnetoresistance sensor or reproduce head (GMR-DMR) comprising multilayers of alternating magnetic and nonmagnetic thin film layers arranged such that sets of N sandwiched magnetic and nonmagnetic film layers are formed on either side of the center-most, conductive, nonmagnetic or magnetic film layer, whereby the layered structure operates in the fashion of a dual magnetoresistive sensor or reproduce head and exhibits giant magnetoresistance. Preferably the outer-most magnetic layers are of a thickness that differs from the remaining magnetic film layers in order to reduce self-bias level variance between the outermost and innermost magnetic film layers. Sense current flow through the GMR-DMR structure is induced by sensed magnetic fields and generated giant magnetoresistance changes are detected as head output voltage variations.

摘要： A shorted dual MR head which is magnetically shielded for the purpose of isolating the dual MR head from extraneous magnetic fields and from long wavelength recorded signals which could cause nonlinear distortion of the dual MR head but not shielded for the purpose of improving linear resolution. The magnetic shields do not significantly affect linear resolution of the dual MR head and can be spaced apart from the dual MR head over a wide range of separation distances limited by factors other than the characteristic bit length of the magnetic signal to be resolved. In one embodiment, at least one shielding element for the dual MR head can be one of the poles or other components of an inductive record head and, together, the two heads can form an integrated thin-film inductive record/MR reproduce head assembly.

摘要： A lifting belt which really is two belts; a lumbar belt, and an abdominal belt are enclosed. The lumbar belt is the inner belt and has a lumbar compression pad in its mid-rear portion for engaging the fifth lumbar area of the back. The two bodies extending therefrom are of a flexible material generally known as "Spandex". Metal stays are provided vertically adjacent the lumbar compression pad and vertically of the users. Releasable attachment is provided at the two end portions of the lumbar belt, one part being the loop-like material, and the other end having the hook-like material. The end with the hook-like material has loop-like material on its reverse portion. The abdominal belt is secured to the lumbar belt adjacent the lumbar compression pad and desirably has a pair of body portions which extend to their respective ends, and at the ends one has the hook-like releasable attachment member on the inner side, and the loop-like on the outer member. The remote belt end has only the hook-like member on its inside which permits it to overlappingly engage the other end which, in turn, engages the lumbar belt. The method of the invention contemplates the steps of positioning a belt as described on the lifter's body by first engaging the lumbar compression pad in the lower fifth lumbar region, and thereafter securing the lumbar belt at its releasably secured ends. The belt is worn in this fashion with the abdominal band loosely secured to the underlying lumbar belt. At the time of heavy lifting, the user stretches the abdominal belt and overlappingly secures the same firstly to the lumbar belt and thereafter to itself to firmly engage the abdominal muscles and anchor the lumbar compression pad in the lower fifth lumbar region of the back.

摘要： A magnetometer includes a magnetoresistive element and first and second high-permeable laminated flux collectors of height H partially overlapping, respectively, opposing lateral edges of the magnetoresistive element, wherein the flux collectors are separated laterally by a gap of length G which the magnetoresistive element spans. The two laminated flux collector and the magnetoresistive element cooperatively form an open-loop flux-conducting path of total height 2H+G, that is capable of collecting flux of a magnetic field being measured and, in response to the flux collected, developing a magnetometive force across the gap G that is functionally related to the height of the flux collectors.

摘要： A spin accumulation sensor having a three terminal design that allows the free layer to be located at the air bearing surface. A non-magnetic conductive spin transport layer extends from a free layer structure (located at the ABS) to a reference layer structure removed from the ABS. The sensor includes a current or voltage source for applying a current across a reference layer structure. The current or voltage source has a lead that is connected with the non-magnetic spin transport layer and also to electric ground. Circuitry for measuring a signal voltage measures a voltage between a shield that is electrically connected with the free layer structure and the ground. The free layer structure can include a spin diffusion layer that ensures that all spin current is completely dissipated before reaching the lead to the voltage source, thereby preventing shunting of the spin current to the voltage source.

摘要： A method, apparatus, and system are provided for implementing spin-torque oscillator (STO) sensing with a demodulator for hard disk drives. The demodulator measures an instantaneous phase of the readback signal from a STO sensor and converts the readback signal into a signal that is proportional to the magnetic field affecting the STO frequency during a bit time. The converted signal is used for processing by conventional data detection electronics.

摘要： Read sensors and associated methods of fabrication are disclosed. A read sensor as disclosed herein includes a first shield, a sensor stack including an antiparallel (AP) free layer, and insulating material disposed on the sensor stack. A aperture is formed through the insulating material above the sensor stack so that a subsequently deposited second shield is electrically coupled to the sensor stack through the aperture. The width of the aperture controls the current density that is injected into the top of the sensor stack. Also, hard bias structures may be formed to be electrically coupled to the sensor stack. The electrical coupling of the sensor stack and the hard bias structures allows current to laterally spread out as it passes through the sensor stack, and hence, provides a non-uniform current density.
