Abstract
A slider having a pair of rails with elongated surfaces which face the disk and are oriented generally along the direction of motion of the disk; a cavity, inset relative to the rail surfaces, is configured to produce subambient pressure tending to draw the slider toward the disk; at least one of the rail surfaces is interrupted by at least one detail configured to reduce the variation in roll for different yaw angles. In another aspect, a slider has at least one groove cut in at least one rail; the groove is oriented at an angle such that its leading end is nearer the inner end of the rail and its trailing end is nearer the outer end of the rail. Other aspects and features are disclosed.
