US 7,612,968 B1 · Disk drive microactuator frame with epoxy overflow reservoir

Abstract

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).

Dependent claims

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;
and
a first material within at least part of each of said first and second slots;
and
first and second actuators associated with said first and second arms, respectively.

A disk drive slider positioner, comprising:

a frame comprising a base and first and second arms that each cantilever from said base, wherein said base comprises a base protrusion that is located between said first and second arms and that comprises first and second base protrusion sides, wherein said first base protrusion side comprises first and second side sections that are spaced inwardly from said first arm by first and second distances, respectively, and that each define a different portion of a length dimension of said first base protrusion side, wherein said second base protrusion side comprises third and fourth side sections that are spaced inwardly from said second arm by third and fourth distances, respectively, and that each define a different portion of a length dimension of said second base protrusion side, wherein said first distance is different from said second distance, and wherein said third distance is different from said fourth distance;
a first material within at least part of a space between said first arm and said first base protrusion side and within at least part of a space between said second arm and said second base protrusion side;
and
first and second actuators associated with said first and second arms, respectively.
