ABSTRACT:
A method of and apparatus for burnishing a surface of a magnetic disc of a disc drive are disclosed. The disc drive has a data head and an actuator supporting the head as the head flies above the surface of the disc. A controller causes the disc to be rotated at rates of rotation which will result in burnishing head fly heights which are less than a normal operational fly height of the head. An actuator controller controls the actuator to repeatedly move the head across a region of the disc during a burnishing time period. The head flies above the surface of the disc at the burnishing fly heights during the burnishing time period to thereby reduce asperities on the disc.
