Abstract: Approaches for integrated lead suspension that provides many benefits, such as enabling a dual stage actuator (DSA) to be used with a single layer flex with a reduced amount of crosstalk. An integrated lead suspension comprises a tail end having a plurality of conductive pads positioned thereat. The plurality of conductive pads includes a first and second dual stage actuator (DSA) pad. The first and second DSA pads are electrically coupled to a conductive member by way of conductive vias. The conductive member may be a stainless steel island. The first DSA pad conducts a signal to a first terminal at each of a plurality of dual stage actuators, while a second terminal at each of the plurality of dual stage actuators is connected to ground.
