ABSTRACT:
An improved flexure for a disc drive having a rotary head positioning apparatus located within a housing for locating a plurality of magnetic read/write heads relative to recording media within the housing. The flexure is particularly suitable for carrying servo heads and has its primary torsional and lateral bending resonant frequencies above 2.8 Khz and 5.0 kHz respectively. The flexure includes a base portion coupled to the head positioner apparatus, a head portion for carrying the servo head, the head portion including stiffener wings, and a curved portion joining the base and head portions. An extended backplate riveted to the flexure provides additional stiffness to the flexure.
