A magnetic write head and method of manufacture thereof that has a first
pole structure having a step notched first pole structure. The step
notched structure includes a bottom notched portion that is wider than
the second notched portion formed thereover. The upper, or narrower,
notched portion has a width that is substantially equal to and self
aligned with a second pole structure (P2) formed thereover. The invention
may also include first and second wing portions formed in the first pole
that are recessed from the ABS and that extend laterally from the first
notched portions of the first pole. The formation of the winged portions
is assisted by an ion mill resistant bump (alumina bump) formed
thereover, which acts as a mask during the ion milling operations that
are used to form the first and second notches.
