Abstract
A disc drive implementing a dual-stage actuation system having an improved scheme for electrically interconnecting a transducing head to a flexure includes a support structure supporting a slider in proximity to a surface of a rotatable disc. The support structure is coarsely positionable by a main actuator. A microactuator is also provided, including a stator attached to the support structure and a rotor operatively attached to the slider. The rotor is connected to the stator by at least one flexible beam. A first electrical interconnect is formed between the support structure and the stator of the microactuator. A conductive trace is formed on the flexible beam between the stator and the rotor of the microactuator. A second electrical interconnect is formed between the rotor of the microactuator and at least one bond pad on the slider electrically connected to the transducing head.
