Abstract: An operationally contacting hard disk drive system has reduced friction due to lower capillary adhesion between the disk surface (100) and a transducer in a substantially continuous sliding relationship with the surface. The disk surface has an array of protrusions (101) separated by generally flat recesses (102) that arise semispherically on a hard protective layer (104) that lies atop a magnetic medium layer (106), wherein each of those layers reflects the underlying texture layer (98) which is grown atop a silicon substrate (108), after bumps (102) have partially grown, yielding substantially flat sections (112) between the bumps (110). The surface roughness may increase in a radially graded fashion to compensate for the increased linear velocity and concomitant frictional power loss near the outer diameter of the disk. It is important that the uppermost reaches of the textured surface are smooth but not flat in order to obtain lasting low friction operation, which is accomplished by constructing the surface with a highesst approximately one percent having an average radius of curvature in a range between 2 microns and 100 microns. An area of the slider in apparent contact with the disk surface is preferably less than 1000 square microns, and a ratio between this nominal area and the mean to peak height is less than 0.3 meters. The slider may also include a substantial thickness of partially wetting materials having differing wear rates, or may alternatively be textured with deep grooves or materials having differing wear rates, in order to provide reduced frictional adhesion despite wear of the slider.

Abstract: A system for lapping transducers (28) has an abrasive surface (22) that communicates with the transducers to provide information for controlling the lapping of the transducer. The lapping body (20) communicates with a transducer (28) with a signal that the transducer is designed to read or write. For lapping a magnetic head or slider, the lapping body contains a magnetic medium layer (23) that is prerecorded or written by the head during lapping, while the signal received by the head is monitored by a processor (32) in order to terminate lapping.

Abstract: A transducer (48) for a hard disk drive has a magnetic core (66) and a pair of poletips (44) that project transversely from the core for sliding contact with the disk during reading and writing. The transducer is formed entirely of thin films in the shape of a low profile table having three legs that slide on the disk, the poletips being exposed at a bottom of one of the legs for high resolution communication with the disk, the throat height of the poletips affording sufficient tolerance to allow for wear. The transducer includes a loop shaped core of magnetic material that ends at the poletips, the core extending further parallel than perpendicular to the disk surface. The dimensions of the yoke adjacent to the poletips are designed to avoid saturation at the poletips by saturating at a lower flux in the yoke than the poletips.
