Abstract

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.

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.
