METHOD FOR MANUFACTURING A MAGNETIC WRITE HEAD HAVING A WRITE POLE TRAILING EDGE TAPER

摘要

A method for manufacturing a magnetic write head for perpendicular magnetic data recording, having a write pole with a tapered trailing edge for improved write field at small bit lengths. The trailing edge taper is formed by a deposition process that can be performed after the write pole flare point has already been formed, and especially after a wrap around shield side gap has been formed. This advantageously allows the distance between the write pole flare point and the trailing edge taper to be closely controlled.
