A method for controlling the formation of the trailing shield gap during
perpendicular head fabrication and head formed thereby are disclosed. The
in-situ trailing shield gap deposition process removes the pre-sputter
process that can damage the write pole material. Further, a seed
pre-layer is formed on top of the trailing shield gap to absorb any
non-uniformity of the trailing shield gap and to control issues resulting
from the pre-sputter process originating from the trailing shield seed
deposition.
