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.

Head arm flexure for disc drives

An improved flexure mounting arrangement for a disc drive system having a head positioning apparatus located within a housing for locating a plurality of magnetic read/write heads relatvie to recording media disposed within the housing. The mounting system includes one or more flexure mounts each having a base, a pair of attachment arms each having a screwhole extending longitudinally therethrough and a flexure support pad. The attachment arms extend from opposite sides of the base and are substantially symmetrical about the longitudinal axis of the flexure. A pair of longitudinally extending screws may thus be used to secure the flexure mount to the head positioning apparatus. The flexure support pad is thinner than the base and extends distally therefrom. The top and bottom surfaces of the support pad are adapted to engage separate flexures, thereby allowing the flexure mount to support one or two flexures independently of any other flexures within the disc drive.
