Reverse Process Burnishing Method for Disk Surfaces

      Described is a process for burnishing thin film disks in the
reverse rotation of the texture application.

      The texture is put on by rotating a disk in either a clockwise
or counter clockwise direction.  This process leaves burrs and edges
sticking up above the surface.  Burnishing in the same direction of
the texture creates a burr as shown in the figure (labeled old burr).
By burnishing with either a head or tape in the opposite direction,
you can remove or lay down the burrs back into their original groove
as shown in the Figure (labeled new burr).
