Glass Burnish Disk

      A method for burnishing and cleaning sliders during flyheight
testing over a glass disk is disclosed.  The slider is burnished by
flying it over an etched burnish track at a relatively low RPM.

      A burnish track is etched into the current glass disk that is
used for flyheight testing.  The etched pattern is limited to a band
at the outer diameter of the disk and is shown in the figure.  The
pattern shown is one that is known to work; there may be other
patterns that would also work effectively.

      When flyheight testing head suspension assemblies, the head is
first flown over the burnish track at a relatively low RPM (low
enough to insure sliding contact with the disk).  The burnish track
burnishes and cleans the head to insure an accurate flyheight test
measurement.
