    摘要： A polishing system and associated methods are described for polishing a magnetic disk used in a disk drive system. The polishing system includes a polishing film that is used to polish the magnetic disk. The polishing system also includes an actuator operable to move the polishing film across a surface of the magnetic disk to polish the magnetic disk. The polishing system also includes a pad having at least one protrusion extending from a surface of the pad. The protrusion is configured to contact the polishing film and press the polishing film against the magnetic disk. The protrusion is operable to compress to about the surface of the pad when in contact with the polishing film. Once polishing is complete, the pad retracts from the polishing film and the protrusion extends from the pad, reducing the adhesion force between the pad and the polishing film.
