    摘要： A method is disclosed for independently controlling track width and bevel angle of a write pole tip having a P3 pole tip for perpendicular recording. The method includes establishing the track width in a portion of the P3 layer material. A portion of this portion having the established track width is protected by providing a temporary masking material to make a protected portion. At least one unprotected portion is left exposed to be shaped. This unprotected portion is then beveled to produce at least one beveled portion having a bevel angle. The protected portion produces a rectangular portion which together with the beveled portion produce a hexagonal pole tip. Also disclosed is a magnetic head having a hexagonal pole tip, and a disk drive having a magnetic head having a hexagonal pole tip.

    摘要： One preferred method for use in making a magnetic write head with use of the resist channel shrinking solution includes the steps of forming a first pole piece layer of a first pole piece; forming a gap layer over the first pole piece layer; forming a patterned resist over the first pole piece layer and the gap layer; electroplating a first pedestal portion of a second pole piece over the gap layer within a channel of the patterned resist; forming an oxide layer over the first pedestal portion; applying the resist channel shrinking solution comprising the resist channel shrinking film and the corrosion inhibitors over the patterned resist; baking the resist channel shrinking solution over the patterned resist to thereby reduce a width of the channel; removing the resist channel shrinking solution; electroplating a second pedestal portion of the second pole piece within the reduced-width channel of the patterned resist; removing the patterned resist; and milling the structure. Advantageously, the oxide layer and the corrosion inhibitors of the resist channel shrinking solution reduce corrosion in the pole piece during the act of baking the resist channel shrinking solution.

    摘要： In the formation of the top magnetic write pole in a thin film magnetic recording head, a CMP stop layer comprising rhodium is deposited over the Al2O3 layer that overlies the top magnetic pole. A mixture of silicon dioxide, ammonium persulfate and benzotriazole is employed as a slurry in the CMP process that removes the portion of the Al2O3 layer covering the top magnetic pole. This eliminates the need for an extra thick layer of Al2O3 to be first deposited over the top pole and then removed to expose the top pole. The magnetic layer that forms the top pole can be plated to the target thickness of the top pole. As a result, the thickness of the photoresist layer that is used to define the size and shape of the top pole can be decreased to a desirable thickness, facilitating the use of DUV radiation to expose the photoresist layer.

    摘要： A magnetic write head and method of manufacture thereof that has a first pole structure having a notched structure configured with a steep shoulder portion and a narrow vertical notch portion extending from the top of the steep shoulder portion. The write head also includes a second pole structure (P2) that has a very narrow width (track width) and that is self aligned with the narrow vertical notch structure of the first pole structure. The write head provides excellent magnetic properties including a very narrow track width and minimal side writing, while avoiding magnetic saturation of the poles.

    摘要： A lead overlay design of a magnetic sensor is described with sensor and free layer dimensions such that the free layer is stabilized by the large demagnetization field due to the shape anisotropy. In one embodiment the giant magnetoresistive (GMR) effect under the leads is destroyed by removing the antiferromagnetic (AFM) and pinned layers above the free layer. The overlaid lead pads are deposited on the exposed spacer layer at the sides of the mask that defines the active region. In other embodiment a layer of electrically insulating material is deposited over the sensor to encapsulate it and thereby insulate it from contact with the hardbias structures. Various embodiments with self-aligned leads are also described. In a variation of the encapsulation embodiment, the insulating material is also deposited under the lead pads so the electrical current is channeled through the active region of the sensor and sidewall deposited lead pads.
