  • Patent number: 8717713
    Abstract: An improved dual stage actuated disk drive head suspension in accordance with one embodiment of the invention includes a mounting/base plate having first and second portions connected by a linkage, one or more PZT motors and a flexure having one or more pairs of differential drive signal traces. Each PZT motor has a pair of electrodes. Non-conductive adhesive secures each PZT motor to the first and second portions of the mounting/base plate with the electrodes of each motor being electrically isolated from the mounting/base plate. Each pair of drive signal traces is electrically connected to one of the pair of PZT motor electrodes to couple differential electrical drive signals to the PZT motor. Each PZT motor drives the first and second portions of the mounting/base plate with respect to one another in response to the drive signals.
