Abstract: Implementations described and claimed herein include a method for manufacturing monolithically-integrated on-slider hybridized electronics for magnetic read/write. The method includes forming a slider body, excising a void in a surface of the slider body, monolithically integrating an electronic block into the void of the slider body, polishing the surface of the slider body, and depositing functional layers on the surface of the slider body. By integrating electronics in close proximity to transducers, operational performance and functionality may be gained.

Abstract: A data reader may be configured with at least a detector stack positioned on an air bearing surface and consisting of a spin accumulation channel continuously extending from the air bearing surface to an injector stack. The injector stack can have at least one cladding layer contacting the spin accumulation channel. The at least one cladding layer may have a length as measured perpendicular to the ABS that filters minority spins from the detector stack.

Abstract: A lateral spin valve reader that includes a detector structure located proximate to a bearing surface and a spin injection structure located away from the bearing surface.

Abstract: A lateral spin valve reader includes a channel layer having a first end that is proximate to a bearing surface and a second end that is away from the bearing surface. The lateral spin valve reader also includes a detector structure disposed over an upper surface of a first portion of the channel layer that is proximate to the first end of the channel layer. A spin injection structure disposed below a lower surface of a second portion of the channel layer is proximate to the second end of the channel layer. An area of overlap between the spin injection structure and the second portion of the channel layer is substantially larger than an area of overlap between the detector structure and the first portion of the channel layer.

Abstract: A disc drive head that includes a shared pole having high magnetic anisotropy layer which locally decreases the amplitude of dynamic field excitation of the shared pole at the write operation frequency to reduce side-writing of a disc media during a write operation.

Abstract: A magnetic recording head having an air bearing surface for confronting a surface of a rotating disc and comprising a pole tip and a generally rounded and substantially planar body attached to the pole tip is disclosed. The width of the pole tip defines a track width of data written to the rotating disc. The generally rounded shape of the top pole body is such that top pole magnetization gradually changes its direction and follows the edges of the body. Further, the pole tip has low remanence, gradual spin structure and no domain walls formed near the pole tip.

Abstract: A magnetoresistive sensor having two free layers with shape anisotropy induced magnetic alignment is disclosed. The magnetoresistive sensor includes a first ferromagnetic free layer having a first quiescent state magnetization direction. The magnetoresistive sensor also includes a second elongated free layer having a second quiescent state magnetization direction and positioned such that the first quiescent state magnetization direction is generally orthogonal to the second quiescent state magnetization direction. Further, a portion of the second ferromagnetic free layer overlaps a portion of the first ferromagnetic free layer proximal to an air bearing surface to form a v-shape. A nonmagnetic spacer layer is also positioned between the first ferromagnetic free layer and the second ferromagnetic free layer.

Abstract: Data is written to a magnetic media, by applying a magnetic write field to the magnetic media with a write pole, in conjunction with a high frequency magnetic field, to the magnetic media to assist writing to the magnetic media. The high frequency magnetic field is generated by applying a specific write current waveform to the magnetic writer, resulting in the generation of a high frequency magnetic write field.

Abstract: A magnetic field sensor for detecting fields applied from an adjacent medium such as a disc has an air-bearing surface and includes a pinned layer, a free layer, and a spacer layer between the pinned layer and the free layer. The free layer has a first width at the air-bearing surface and a second width smaller than the first width at a position spaced from the air-bearing surface. In one embodiment, the free layer may be generally triangular in shape. The pinned layer and spacer layer may also be generally triangular in shape.

Abstract: A spin valve sensor is disclosed that comprises a first layer of ferromagnetic material and a second layer of ferromagnetic material. A first layer of non-ferromagnetic material is positioned between the first and second layers of ferromagnetic material. A pinning layer is positioned adjacent to the first layer of ferromagnetic material such that the pinning layer is in contact with the first layer of ferromagnetic material. The spin valve includes synthetic antiferromagnetic bias means extending over passive end regions of the second layer of ferromagnetic material for producing a longitudinal bias in the passive end regions of a level sufficient to maintain the passive end regions in a single domain state. A method for forming a spin valve sensor with exchange tabs is also disclosed.

Abstract: The present invention provides a method for forming a dual giant magnetoresistive sensor. First and second spin valves are first formed and arranged such that a dielectric layer is positioned between the first and the second spin valves. The first spin valve has a plurality of layers including a first antiferromagnetic layer and a first pinned layer. The second spin valve has a plurality of layers including a second antiferromagnetic layer and a second pinned layer. First and second currents are supplied respectively to first and second spin valves. The first current generates a first magnetic field on the first pinned layer that orients a magnetization of the first pinned layer in a first desired direction. The second current generates a second magnetic field on the second pinned layer that orients a magnetization of the second antiferromagnetic layer in a second desired direction.

Abstract: A bottom shield for use in a magnetic read head is disclosed. The bottom shield has a ferromagnetic layer that has a length and an outer width. The ferromagnetic layer has a first edge, a second edge opposite the first edge, and an air bearing surface. The first edge and the second edge are each normal to the air bearing surface. A plurality of notches are located along both the first edge and the second edge. The plurality of notches form a plurality of narrow widths that are each narrower than the outer width so that one of a plurality of magnetic domain walls is located at each of the plurality of narrow widths.
