A read/write head for use in a perpendicular magnetic recording head in a
data storage system. The read/write head includes a write section that is
comprised of a first pole layer, a second pole layer, a third pole layer,
and a shield layer. The third pole layer defines a write pole tip, and
the third pole layer and the shield layer are separated from each other
to define a write gap therebetween. At least part of the shield layer has
a generally uniform width, and wherein the write pole tip defines a track
width that is substantially equal to the uniform width of the shield
layer. According to one embodiment the entire shield layer has a
generally uniform width that is substantially equal to the track width.
According to another embodiment, the shield layer includes a lower
section and an upper section, wherein the lower section has a generally
uniform width along its entire length, and wherein the upper section is
wider than the lower section.
