| 20090316298 | MAGNETIC DISK DEVICE AND HEAD SLIDER - A head slider suppresses variation in a floating amount of the head slider, floating over a discrete medium, even when the floating amount is small. Among a plurality of pads of the head slider, the shape of the pad provided on the outflow end portion is formed of a wedge shape having a width narrowing toward the air outflow end. Thus, the pressure distribution can be improved, and the air pressure can be averaged. Accordingly, it becomes possible to suppress the variation in the floating amount caused by the discrete medium groove, enabling stable floatation. Moreover, because the stable floatation with a small floating amount can be attained, high-density recording/reproduction can be achieved with accuracy. | 12-24-2009 |
