ABSTRACT:
A disk drive flexure has a pattern of voids in the ground plane in the area directly underneath the read and write bond pads, in order to adjust the respective impedances of the read and write bond pad pairs to match the impedances of the read and write transducers and the signal trace pairs to and from the transducers. The resulting impedance matched bond pads increase the effective signal bandwidth of the flexure and its electrical connections, decreasing the probability of error at high signal speeds and increasing the maximum data rate through the suspension.
