Low Rotation Per Minute Burnishing Procedure with Optimized Rotation
Per Minute

      Disclosed is a Low Rotation Per Minute (RPM) Burnishing
procedure with variable RPM.

      Current Low Rotation Per Minute Burnishing (LRB) uses a fixed
RPM to remove the Thermal Asperity (TA) from disk surface.  It has
been found that determining the appropriate RPM is difficult, and
consecutive LRB has resulted in disk/head wear.

      The LRB shown in the Figure will monitor the Soft Error Rate
(SER) at the vicinity of TA before and after the LRB to determine an
optimum RPM if a if consecutive LRB is neccesary.

      This feedback mode will eliminate any excessive stress applied
to the interface due to a fixed LRB mode.

      An example of the procedure is given in the Figure.
