Flexure for minimizing fly height modulation of near-contact recording sliders in a disk drive

摘要

A flexure mounted slider and its method of fabrication is described, wherein the slider is affixed to a pair of highly compliant, transverse (to the longitudinal axis of a load beam) crossbars whose common axis passes directly above the center of percussion of the slider. The location of the center of percussion of the slider relative to the flexure eliminates translational motion of the slider during HDI events, but not twisting motion in a pitch direction during normal operation, and thereby minimizes the transfer of kinetic energy between the slider and the flexure during HDI events with a hard disk. The high compliance of the flexure crossbars to twists in a pitch direction, as well as the compliance of the outriggers to bending, allows the slider to pass over irregularities in the disk during normal operations.
