The spring metal layer includes a base region, support arms extending from the base region, and a slider mounting region. The slider mounting region includes a proximal portion, a distal portion, and a pair of motor openings. The motor openings are configured to receive motors such that the longitudinal axes of the motors are non-parallel with the longitudinal axis of the slider mounting region. The suspensions include traces that include a base portion on the base region of the spring metal layer, a spring metal-unsupported portion extending from the base region to the slider mounting region, and a slider mounting portion extending from the spring metal-unsupported portion onto the slider mounting region. And, the suspensions include an insulating layer between portions of the spring metal layer and the conductor layer.”
