Abstract:
Methods are provided for fabricating a write head with a self aligned wrap around shield and a self aligned flared region of a write pole. A flare point and a track width of a write pole may be fabricated using multiple processes. The multiple processes utilize several masking structures to define the track width and the flare point of the write pole. A mask structure is formed to cover a first portion of the write pole. An edge of the mask structure adjacent to an exposed second portion of the write pole defines a flare point of the write pole. Various structures of the write head, including shield gap layers, a wrap around shield and a flared region (e.g., the yoke) of the write pole may be fabricated from the flare point defined by the mask structure.
