Patent ID: 8347489

Claim:
A method for manufacturing a magnetic write head, comprising: depositing a magnetic write pole material; forming a write pole defining mask structure over the magnetic write pole material; performing an ion milling to remove a portion of the magnetic write pole material, thereby forming a magnetic write pole; depositing a non-magnetic side gap material; forming a side shield defining mask having an opening configured to define a side shield; depositing a magnetic material into the opening in the side shield defining mask to form first and second magnetic side shields; removing the side shield defining mask; depositing a non-magnetic fill layer; performing a chemical mechanical polishing; performing an ion milling to remove a portion of the non-magnetic side gap layer that extends over the write pole; forming a tapered trailing edge surface on the write pole; depositing a non-magnetic trailing gap layer; and forming a trailing shield over the non-magnetic trailing gap layer.
