Rounded Chamfer Slider

      Disclosed is a slider design used in hard disk drives to
improve static shock resistance.

      If shock is applied to hard disk drive at rest, each of sliders
starts to roll on an adjacent disk surface shown in Fig. 1.  At that
time, the sharp edge of the slider hits the disk surface and the
pressure at the edge becomes much higher.  This high pressure makes
damage on the disk surface.  If there exists disk damage, the head
can not read the data on the damaged surface anymore.

      In order to reduce the high pressure at the edge of the slider,
even if the slider rolls, we make rounded chamfer at the edge of the
slider as shown in Fig. 2.  This improves the static shock
resistance.
