1. A suspension assembly, comprising:
a tri-stage suspension comprising:
a mount plate attached to a distal end of a load beam;
a first actuator shaped as a non-right angle parallelogram and spanning across a first opening in the mount plate; and
a second actuator shaped as a non-right angle parallelogram and spanning across a second opening in the mount plate, wherein each of the first actuator and second actuator include a first set of parallel sides extending along a length of the tri-stage suspension at an angle and a second set of parallel sides extending along a width of the tri-stage suspension at an angle, with the first set of parallel sides are longer than that of the second set of parallel sides.
