30. Nepela teaches at col. 3, ll. 4-8:
FIG. 1 is a plan view of the air bearing surface of a
negative pressure air bearing slider, according to this invention;
FIG. 1a is a side view of the negative pressure air bearing
slider of FIG. 1[.]
31. Nepela teaches at col. 3, ll. 38-49:
With reference to FIGS. 1 and 1a, a rectangular slider
body 24 has a length L1, a width designated by reference
numeral 19 and a thickness designated by numeral 28. The
slider 24 is configured with raised side rails 10 and 12, tapered
regions 22 at the leading edge of the slider and a central pad 8
formed adjacent to the central taper 22. The tapered regions 22
are of identical length from the leading edge. The tapered
regions 22 have a taper angle (shown at 20 in FIG. 1a) which
may be in the order of 20 minutes to 60 minutes. A negative
pressure cavity 18 is formed by etching between the central pad
8 and side rails 10, 12 and extending to the trailing edge of the
slider.
32. Thus Nepela describes “a rectangular slider body,” “[a] leading
edge of the slider,” and “[a] trailing edge of the slider.”
33. Nepela teaches at col. 3, ll. 21-24:
FIGS. 5a-5d are plan views of alternative embodiments
of a negative pressure air bearing slider with a modified center
rail structure, negative pressure regions associated with the side
rails of the slider, and an additional rear pad[.]
34. Nepela also teaches at col. 5, ll. 40-60:
FIG. 5a illustrates another embodiment of a negative
pressure air bearing slider having two side rails 112, 114, a
