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.

摘要： Glide test systems and associated methods are described. A glide test system includes a glide test head that is flown over the surface of a recording disk to detect asperities on the recording disk. The glide test head includes a detection pad on the trailing end of the head. Heating elements are fabricated proximate to the detection pad. The heating elements are independently controllable to control the amount of protrusion of different regions of the detection pad. The heating elements thus provide a way to substantially flatten the detection surface of the detection pad, and compensate for an uneven topography on a detection surface.

摘要： Disclosed is a method and apparatus for sensing the vibrational response of a slider of predetermined dimensions during contact with one or more surface asperities on a recording surface, separating the response into its individual bending mode frequency component responses, determining one or more bending mode frequency responses which display monotonic behavior with increasing asperity interference, and designing a mode selection sensor optimized to detect the monotonic bending mode frequency identified. The mode enhanced sensor is designed by first analyzing the stress distribution of the slider corresponding to the monotonic bending mode frequency, identifying regions of the slider which experience substantially positive or substantially negative stress, and partitioning the upper conductive layer of a piezoelectric sensor to form a partitions corresponding to each of the identified regions. The sensor may be further enhanced by tailoring the partitions to exclude undesirable stress contributions.

摘要： An enhanced piezoelectric sensor for detecting a predetermined bending mode frequency in the vibrational response of a slider with dimensions smaller than the conventional 100% slider during contact with one or more surface asperities on a recording surface. A method for making the enhanced sensor is also disclosed. The sensor comprises a substantiality rectangular slab of piezoelectric material having a charge response which corresponds to in-plane stress under free boundary conditions. Enhancement is achieved by partitioning an upper conductive layer along the lines of symmetry of the slider's stress distribution, which is related to the piezoelectric material's generated charge. In the preferred embodiment, the conductive layer is partitioned into two electrically isolated regions symmetric about the sensor's lateral axis. The design facilitates the isolation of a high frequency bending component which has been found to be monotonic with increasing surface asperity interference.
