Abstract
A micro actuator having separated stages and a data storage apparatus employing the same are provided. The micro actuator includes: a supporting unit; stages that are elastically supported by the supporting unit, each stage having a mounting surface where a target driven body is mounted thereon, and arranged adjacent to each other; levers which are disposed between the stages, each lever having two ends respectively connected to adjacent stages, and which apply force to the adjacent stages so that when one of the stages is moved, an adjacent stage is moved in an opposite direction to a moving direction of the moved stage; and driving units which respectively provide a driving force to the stages.
