• The recording density of magnetic hard disc drives(HDD)has been increasing with astonishing speed. The technical leap which allows much narrower data track width is expected. This requires high bandwidth servo position control of the read/write(R/W)head because the head must follow the narrow data track with high accuracy. A slider driven device, which including a pair of moonie piezoelectric(PZT)microactuators and a frame holder, is invented to achieve more accurate positioning of the magnet haed and to increase the servo bandwidth. The moonie PZT microactuator is designed to amplify the actuating displacement. The stroke of displacement is about ±0.5 μm with a drive voltage of ±20V. The dynamic performances of the PZT microactuator are evaluated by finite element method(FEM). Comparing to the I-shape PZT microactuator[1], the shock resistance of the moonie PZT microactuator is much better.
