Concurrent Mag and Glide Testing via Constant Flyheight Glide at
Mag Speed

      The following describes the process of achieving concurrent
glide and magnetic testing via the use of a constant flyheight glide
test at the magnetic test speed.

      To create the constant glide profile at magnetic speed you must
model the glide head air bearing profile to achieve the proper skew
at the inner and outer diameter radiuses at the magnetic test speed.
The glide head is then rotated about the center of the media until
the inner diameter's head position is parallel to the outer diameter.
The centerline between the new head positions creates the radial path
that the linear stage must travel on and the new skew that the head
fixturing must have.

This is then combined at the tester to overlap the magnetic test.
