Patent ID: 7242132

Claim:
A head assembly, comprising: a suspension having a gimbal; a flexible printed wiring sheet having a plurality of first conductor patterns for piezoelectric actuator driving, a plurality of first pads individually connected to ends of said first conductor patterns, a plurality of second conductor patterns for head element driving, and a plurality of second pads individually connected to ends of said second conductor patterns, said flexible printed wiring sheet being adhered to said suspension except said first pads such that said first and second pads are positioned on said gimbal, said first pads being left unattached to said suspension; a first piezoelectric actuator having a first face, a second face on the opposite side to said first face, a first end, a second end, a plurality of first electrodes, a plurality of second electrodes provided alternately with said first electrodes, a first adhesion portion provided on said first face adjacent said first end, and a second adhesion portion provided on said second face adjacent said second end, said first piezoelectric actuator being adhered at said first adhesion portion thereof to said gimbal; a second piezoelectric actuator having a third face on the same side as that of said first face, a fourth face on the opposite side to said third face, a third end on the same side as that of said first end, a fourth end, a plurality of third electrodes, a plurality of fourth electrodes provided alternately with said third electrodes, a third adhesion portion provided on said third face adjacent said fourth end, and a fourth adhesion portion provided on said fourth face adjacent said third end, said second piezoelectric actuator being disposed substantially in parallel to said first piezoelectric actuator and adhered at said third adhesion portion thereof to said gimbal; a head slider mounted on said first and second piezoelectric actuators and adhered to said first piezoelectric actuator at said second adhesion portion and to said second piezoelectric actuator at said fourth adhesion portion, said head slider having a head element and a plurality of terminals connected to said head element; and elements for individually connecting said second pads to said terminals; said first pads being individually connected to said first, second, third and fourth electrodes.
