A head stack assembly for a disk drive includes an actuator body. The actuator body includes a pair of sides, a bore defining a longitudinal axis, a first slot extending between the pair of sides, a second slot extending along a direction perpendicular to the longitudinal axis, the second slot extending from the first slot to the bore. The head stack assembly further includes a coil portion cantilevered from the actuator body in one direction and an actuator arm cantilevered from the actuator body in a direction opposite from the coil portion.
