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). ## Claims ### Claim 1 A disk drive slider positioner, comprising: a frame comprising a base and first and second arms, wherein said base comprises first and second base sections, wherein said first and second arms are spaced along said first base section and cantilever from said first base section, wherein said second base section is located between said first and second arms and is spaced inwardly from said first and second arms to define first and second slots, respectively, wherein said first and second slots each comprise at least two different widths along a corresponding length dimension of said first and second slots;
