A write pole tip for a magnetic head has a trailing edge that is closer
than a leading edge to a perpendicular recording medium, so that the
write signal strength of the trailing edge is greater than that of the
leading edge. Such an angled pole tip can write a sharp magnetic pattern
with the trailing edge, reducing erroneous writing. A layer of physically
hard material such as diamond-like carbon (DLC) may adjoin the trailing
edge, the physically hard material layer protruding slightly after
polishing of the media-facing surface due to its resistance to lapping.
This can form an acute corner of the write pole tip adjacent to the
physically hard material layer. The trailing edge may be longer than the
leading edge, and the write pole tip may have a trapezoidal shape.
