Slider with Cornered Air Bearing Surface

      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 as shown shown in Fig. 1.
At that time, the sharp edge of the slider hits the disk surface and
makes damages because contact area of the sharp edge is almost point
and its pressure is very high.  Once the disk surface is damaged, the
head can not read the data on the damaged surface anymore.

      In order to reduce this damage, the contact area of the slider
should be larger.  One solution is to make rounded chamfer at the
edge of the slider.  However, it is very difficult to make that
shape.

      Fig. 2 shows a slider with cornered air bearing surface.  This
design has a large contact area and improves the static shock
resistance of the hard disk drives.  In addition, it is easy to make
such sliders by etching process.
