Disk drives including head suspensions within dual stage actuation systems have improved electrical connectivity between electrical connection pads from flexible circuits as are applied to head suspension assemblies with piezoelectric microactuators as also provided to head suspension assemblies. A more robust electrical connection provides for better control of microactuator actuation for fine movements and positioning of magnetic read/write heads relative to disk data tracks as part of dual stage actuated suspension systems. Electrical connections utilize conductive epoxy for physically and electrically connecting electrically conductive trace connection pads with one or more surfaces of piezoelectric microactuators. Electrical connections include better conductivity by utilizing plural surface portions of electrical connection pads. The result is a more robust and predictable performance for high data resolution within disk drives.
