|Abstract:||With the trend of decreasing error tolerance in hard disk drives (HDDs), researchers are motivated to search for alternative technologies that can meet the challenges of future disk-drive generations. A secondary stage actuator placed near the head-slider shows potential for this application. Specifically, a lightweight, secondary-stage actuator placed close to the point of control performs better than a single-stage actuator in regulating the position of the read/write head above the center of the track. Currently, efforts are underway in industry and in many research organizations to find solutions that can help sustain the growth rate of track density.|
