Abstract
A head positioning apparatus for positioning a magnetic head in a multi-track tape drive is provided. The apparatus has a voice-coil, a movable carriage supporting the magnetic head and the voice coil, and a center magnetic pole housed in an interior of the voice coil. A pair of outer magnetic poles are positioned opposite each other about the voice coil. First and second flexures are each attached at opposing ends to the outer magnetic poles and in a central portion to the movable carriage. Each of the first and second flexures have one slot near where the first and second flexures are attached to the outer magnetic poles and a pair of slots positioned opposite each other about the area where the first and second flexures are attached to the movable carriage. The first and second flexures each have a plurality of reduced thickness areas and a plurality of increased thickness areas. Each of the increased thickness areas is positioned between adjacent ones of the reduced thickness areas. Each end of the first and second flexures has a plurality of holes for attaching the flexure to the outer magnetic pole and a plurality of holes in the central portion for attaching the flexure to t…
