METHOD OF MANUFACTURING A PERPENDICULAR MAGNETIC WRITE HEAD WITH STEPPED TRAILING MAGNETIC SHIELD WITH ELECTRICAL LAPPING GUIDE CONTROL |
摘要 |
A method for manufacturing a magnetic write head having a stepped trailing shield. The stepped trailing shield is formed by forming a non-magnetic bump over a write pole prior to electroplating a wrap-around magnetic shield. The method allows the location of the front edge of the bump relative to the back edge of the wrap-around shield to be monitored by measuring the electrical resistance of an electrical lapping guide formed concurrently with these features. This concurrent formation of a lapping guide can be used to define the relative location of other features as well, such as the location of a back edge of a wrap-around shield relative to a flare point of a write pole.
