    摘要： A method of reducing flux leakage between a main pole and a wrap around shield (WAS) is provided. A gap underneath a main pole is etched. Magnetic material is deposited in the gap. A layer of nonmagnetic material is deposited on the magnetic material, wherein the layer of nonmagnetic material reduces flux leakage between the main pole and the WAS.

    摘要： A magnetic write head for perpendicular magnetic recording. The write head has a secondary flare point defined by magnetic structures that extend from the sides of the write pole, but not over the trailing edge of the write pole. The magnetic structures each have a front edge that defines the secondary flare point. By constructing the magnetic structures so that they only extend from the sides of the write pole and not over the write pole, they can be formed by electroplating, while leafing the mask structure (used to define the write pole) still intact, thereby greatly simplifying manufacture and preventing damage to the write pole during manufacture.

    摘要： Write elements and methods of fabricating magnetic write poles are described. For one method, a vertical mask structure is formed on a magnetic layer in locations of a pole tip and a yoke of a write pole. The vertical mask structure may be formed by coating vertical surfaces of resists with an atomic layer deposition (ALD) process or a similar process. A removal process is then performed around the vertical mask structure to define the pole tip and part of the yoke of the write pole, and the vertical mask structure is removed. A lower portion of the pole tip is them masked while the upper portion of the pole tip and the part of the yoke is exposed. The upper portion of the pole tip and the part of the yoke are then expanded with magnetic material, such as with a plating process.
