Abstract
Cleaning or polishing magnetic recording media (MRM) may comprise mounting and rotating the MRM on a spindle; circulating a tape adjacent to a surface of the MRM; and applying an electrostatic (ES) voltage to the tape and attracting particles located on the MRM to the tape. The ES voltage may apply an ES load to the tape to force the tape into contact with the surface of the MRM. No mechanical load may be applied to the tape to force the tape into contact with the surface of the MRM. Additionally, a mechanical load may be applied to the tape to force the tape into contact with the surface of the MRM.
