central pad 104 and a rear pad 120. The rear pad 120 has a
trailing edge on which a magnetic transducer is disposed.

The embodiment of FIG. [5a] includes negative pressure
cavities 128a that are associated with each side rail 112, 114
and a central negative pressure cavity 128 that extends from the
center pad.
35. Nepela also teaches at col. 5, ll. 61-65:
FIGS. 5b-5d show modifications of the slider of FIG. 5a,
wherein the center pads 106, 108, 110 are modified to
accommodate different skew/velocity ranges for different
applications used with negative pressure air bearing sliders of
the instant invention.
36. Figure 5c shows Nepela’s center pad 108 is U-shaped with
three walls (unlabeled). The center pad walls consist of a front wall and two
walls that extend from sides of the front wall towards the trailing edge of the
slider.
37. Nepela also teaches at col. 7, ll. 39-41:
The symmetrical design relative to the longitudinal axis of the
slider allows the sliders to be used as UP or DOWN magnetic
heads.
Thus, rear pad 120 is centered with respect to the longitudinal axis of the
slider body.
38. Reissue claims 21, 30-32, and 41 are anticipated by Nepela.
