A disk drive slider positioner (180) includes a frame (184) having a pair
of arms (216a, 216b) that cantilever from a base (188). A slider (140) is
positioned within frame (184). A pair of slots (224a, 224b) extend down
through the frame (184) and also extend along part of the corresponding
arm (216a, 216b). Each slot (224a, 224b) includes a corresponding first
slot section (228a, 228b) and a wider corresponding second slot section
(232a, 232b). A material (240) that is more pliable than the frame (184)
preferably occupies the entire length of each first slot section (228a,
228b). Excess first material (240) may overflow into the corresponding
wider second slot section (232a, 232b), thereby reducing the potential
for excess first material (240) occupying any portion of the space
between a leading edge (144) of the slider (140) and the frame (188).
