Abstract
A dual loop flex circuit for conducting signals between heads of an actuator carriage assembly and an electrical circuit board and for supplying power to a voice coil is provided. The first loop conducts the signals between the heads and the second loop supplies power to the coil. Each loop is mounted in part on a shroud which serves as an anchor for the loops. The other parts of the loops are attached to opposite sides of the actuator carriage assembly such that forces exerted on the actuator carriage assembly by the first loop are canceled by forces exerted on the actuator carriage assembly by the second loop.
