DSA suspension with improved microactuator stroke length
Abstract:
In a dual stage actuated (DSA) suspension, a PZT microactuator is electrically and mechanically bonded to the rest of the suspension by non-conductive epoxy on the front and rear bottom faces of the PZT, by conductive epoxy that bridges a gap between the top face of the PZT which defines the ground electrode and an adjacent metallic and grounded portion of the suspension, and further by additional non-conductive epoxy that bridges the gap and which at least partly overlies the conductive epoxy. The additional non-conductive epoxy increases the effective stroke length of the PZT.
