Patent ID: RE40975

Claim:
A disk drive assembly, including: a head suspension assembly in which resonance mode motion can induce strain, the head suspension assembly comprising: a load beam having a proximal end, a distal end, a mounting region on the proximal end, a rigid region adjacent to the distal end and a spring region between the rigid region and the mounting region; a flexure for supporting a read/write head at the distal end of the load beam; and at least one strain transducer circuit on the head suspension assembly for detecting strain therein such that the strain transducer circuit detects resonance mode motion of the head suspension assembly ; a controller connected to the strain transducer circuit, for providing drive signals as a function of the strain detected by the transducer circuit; and an actuator mechanically connected to the head suspension assembly and electrically connected to the controller, for driving and positioning the suspension assembly as a function of the drive signals .
