Abstract
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.
