摘要： A method for making a bit-patterned-media (BPM) magnetic recording disk includes depositing a FePt (or CoPt) alloy recording layer, and then depositing a sealing layer on the FePt layer before high-temperature annealing. The high-temperature annealing causes the FePt to become substantially chemically-ordered in the L10 phase. After annealing, the sealing layer is removed. The sealing layer prevents nanoclustering and agglomeration of the FePt material at the surface of the FePt layer and the sealing layer, which would result in undesirable high surface roughness of the FePt, making patterning of the FePt layer difficult. The FePt layer can be patterned into the discrete islands for the BPM disk either before deposition of the sealing layer or after deposition and removal of the sealing layer. After patterning and removal of the sealing layer, the disk protective overcoat is deposited over the discrete data islands.
摘要翻译：一种制造位图形介质（BPM）磁记录盘的方法包括沉积FePt（或CoPt）合金记录层，然后在高温退火之前在FePt层上沉积密封层。高温退火使FePt在L10相中变得基本化学排序。退火后，去除密封层。密封层防止FePt材料在FePt层和密封层的表面的纳米聚集和聚集，这将导致FePt的不希望的高表面粗糙度，使得FePt层的图案化变得困难。在沉积密封层之前或在沉积和去除密封层之后，FePt层可以被图案化成用于BPM盘的离散岛。在图案化和去除密封层之后，盘保护外涂层沉积在离散的数据岛上。

摘要： In one illustrative example, a magnetic storage device includes a three terminal magnetic sensor having a collector region made of a semiconductor material, a base region, and an emitter region. An insulator layer is formed between the collector region and a slider body which carries the three terminal magnetic sensor. The insulator layer serves to reduce a capacitance otherwise present between the collector region and magnetic media at a magnetic field sensing plane of the three terminal magnetic sensor. Thus, the insulator layer electrically isolates the collector region from the slider body. The structure may be formed through use of a separation by implanting oxygen (SIMOX) technique or a wafer-bonding technique, as examples.

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.

In a first embodiment the write gap layer includes a non-magnetic, non-conductive first sublayer which is preferably comprised of Ta or Ti which is deposited upon the first magnetic pole to act as an adhesion layer. The write gap layer then includes a second sublayer which is formed of a non-magnetic, electrically conductive material which is preferably comprised of Rh or Ru. A P2 pole tip is electroplated upon the second sublayer, where the electrically conductive second sublayer is utilized to conduct electroplating current. In an alternative embodiment the write gap layer includes a third sublayer that is etchable in a reactive ion etch (RIE) process, and formed between the first and second sublayers. The third sublayer is preferably comprised of Ta or Ti.

摘要： A magnetic head having a heat sink structure that is disposed proximate the induction coil to draw heat away from sensitive components of the head. The heat sink is fabricated above the second magnetic pole, and is therefore fabricated subsequent to the fabrication of the more delicate components of the magnetic head. In a preferred embodiment, the heat sink is fabricated photolithographically in the same process steps in which the electrical lead to the center tap of the induction coil is fabricated. The only difference in the magnetic head fabrication process is the modification of the photolithographic mask that is used to create the electroplating trench in which the electrical lead is electroplated, and the change to the mask involves the creation of a second opening within the mask for the creation of an electroplating trench at the location of the heat sink.
