摘要： A patterned perpendicular magnetic recording medium of the type that has spaced-apart pillars with magnetic material on their ends and with nonmagnetic trenches between the pillars is made with a method that allows use of a pre-etched substrate. The substrate has a generally planar surface at the trenches and comprises material that when heated will diffuse into the magnetic recording layer material and chemically react with one or more of the elements typically used in the recording layer. The pillars are formed of material that will not diffuse into the recording layer. After the recording layer is formed over the entire substrate so as to cover both the pillar ends and the trenches, the substrate is annealed. This results in the destruction or at least substantial reduction of any ferromagnetism in the recording layer material in the trenches so that the trenches are nonmagnetic. The annealing does not affect the recording layer on the ends of the pillars because the pillars are formed of material that will not diffuse into the recording layer.
摘要翻译：具有在其端部上具有磁性材料的间隔开的柱和在柱之间的非磁性沟槽的类型的垂直磁记录介质是通过允许使用预蚀刻的衬底的方法制成的。衬底在沟槽处具有大致平坦的表面，并且包括当加热时将扩散到磁记录层材料中并与通常用于记录层中的一种或多种元素发生化学反应的材料。支柱由不会扩散到记录层中的材料形成。在整个基板上形成记录层以覆盖柱端和沟槽两者之后，将基板退火。这导致在沟槽中的记录层材料中的任何铁磁体的破坏或至少显着减少，使得沟槽是非磁性的。退火不会影响支柱端部的记录层，因为支柱由不会扩散到记录层中的材料形成。

摘要： A method and structure for a spin valve transistor (SVT) comprises a magnetic field sensor, an insulating layer adjacent the magnetic field sensor, a bias layer adjacent the insulating layer, a non-magnetic layer adjacent the bias layer, and a ferromagnetic layer over the non-magnetic layer, wherein the insulating layer and the non-magnetic layer comprise antiferromagnetic materials. The magnetic field sensor comprises a base region, a collector region adjacent the base region, an emitter region adjacent the base region, and a barrier region located between the base region and the emitter region. The bias layer is between the insulating layer and the non-magnetic layer. The bias layer is magnetic and is at least three times the thickness of the magnetic materials in the base region.

摘要： A method for predicting the failure of a data storage device having a slider heater is disclosed. For slider heaters exhibiting a decreasing resistance aging characteristic, a failure warning is produced when heater resistance suddenly increases 2 to 5%, or dR/dt changes sign from negative to positive. For slider heaters exhibiting an increasing resistance aging characteristic, a failure warning is produced when the heater resistance suddenly drops 2 to 5%, or dR/dt changes sign from positive to negative. Additionally, random changes in heater resistance exceeding nominal measurement error may also be utilized to produce a failure warning. This method provides advance warning of potential data read/write errors well before the open circuit failure of the slider heater occurs.

摘要： A magnetic head including a media heating device. Following the fabrication of the heating device, a sacrificial layer of material is deposited to protect the heating device during subsequent process steps. Thereafter, write head components, such as write head induction coils and/or a P1 pole pedestal are fabricated above the heating device, and the sacrificial layer is substantially consumed in protecting the heating device during the aggressive etching and milling steps used to create those components. Further components, including a second magnetic pole are thereafter fabricated to complete the fabrication of the write head portion of the magnetic head. The sacrificial layer may be comprised of alumina, or a material such as NiFe that can act as a seed layer for a subsequent head components such as the P1 pole pedestal.

摘要： A a method for fabricating a structure, such as a magnetic head, having two coplanar metallic features of different compositions, both deposited on their own seed layers. The features may be made tall relative to their widths (ie. have a high aspect ratio), and are also very closely spaced. Only a single high-definition, critically aligned photolithographic procedure is used to create the critical structures, avoiding any problem with aligning features produced by multiple procedures. The method is applied to the production of the write structure of a magnetic read/write head, where a portion of the pole structure and the inductive coils are fabricated in the same plane with a close spacing and both having a vertical aspect ratio of more than about 2:1.

摘要： A magnetic structure, such as a pole tip, and method for forming the same includes forming a pole tip layer of magnetic material. A layer of polyimide precursor material is added above the pole tip layer and cured. A silicon-containing resist layer is added above the layer of polyimide precursor material and patterned. The resist layer is exposed to oxygen plasma for converting the resist into a glass-like material. Exposed portions of the cured polyimide precursor material are removed for exposing portions of the pole tip layer. The exposed portions of the pole tip layer are removed for forming a pole tip. Chemical mechanical polishing (CMP) can then be performed to remove any unwanted material remaining above the pole tip.

摘要： A method for manufacturing a pole tip structure for a magnetic head is provided. An etch stop layer is initially deposited after which a transfer layer is deposited. Further deposited is at least one masking layer. Reactive ion etching is then performed to define a trench in at least the transfer layer. A pole tip layer is then deposited in the trench to define a pole tip structure flanked at least in part by the transfer layer. A surface of the transfer layer or etch stop layer then remains in co-planar relationship with a surface of the pole tip structure.
