Abstract
A micro-actuator that reduces suspension tongue stiffness and a method of manufacturing the micro-actuator are disclosed. In one embodiment, the micro-actuator has a base piece with two arms extending from the base piece. The electric contact pads for the arms are situated on the exterior of the arms at the end opposite the base piece. In one embodiment, the electric contact pads are electrically coupled to the same connection plate that the magnetic read/write head is coupled to, reducing the number of connection traces.
