Abstract :
Summary form only given. A new dual-stage actuator for positioning a magnetic head for high-density hard disk drives (HDDs) was proposed and developed. This dual-stage actuator device is characterized by applying the sputter-deposited thin film PZT, instead of the previously proposed bulk type actuator (Y. Soeno et al., IEEE Trans. Magn., vol. 35, pp. 983-987, 1999).
