A magnetic write head structure that maximizes write field strength while
minimizing stray fields. The write pole structure maximizes write field
strength by minimizing saturation of the magnetic pole tips, and
minimizes stray field writing by preventing magnetic fields from
extending laterally from the sides of the magnetic pole. The write head
structure includes a write pole having a pole tip configured with a stair
notched shape and a steep shouldered base beneath the stair notched
portion. This configuration maximizes the amount of flux that can be
delivered to the pole tip while also avoiding stray fields. The magnetic
pole can also be configured with wing shaped extensions that extend
laterally from the pole tip region but which are recessed from the ABS by
a desired amount. The magnetic write head structure can be manufactured
by forming a magnetic pole with a raised portion, depositing a write gap
material over the magnetic pole and then forming a magnetic pedestal over
the magnetic pole and write gap, the pedestal having a width
significantly smaller than the width of the raised portion of the
magnetic pole, a first ion mill can then be performed to notch and trim
the magnetic pole. Then a non-magnetic layer such as alumina can be
deposited and a second ion mill performed to form a stair notched
configuration. An alumina bump can be formed prior to ion milling to
provide a mask for forming the laterally extending, recessed wings in the
pole tip of the magnetic pole.
