Surface Preparation of Head Air-Bearing Surfaces Process and Tooling
Disclosed is
a method of burnishing and creating a etched air
bearing surface on a slider in order to create a burnishing head or
to create a textured pattern on the air bearing surface for
minimizing stiction.
In practice,
a head suspension assembly has micron-sized
particle tape bonded to its rails. This
head is then loaded on a
media disk spinning a low RPM's, and the head is traversed from ID to
OD. By increasing the flexure angle, you
increase the gramload just
as a normal head suspension assembly, thereby providing a gramload
for the product burnishing process. This
surface texture can also be
done by etching the rails themselves.
