摘要：

Fine positioning by a piggy-back actuator is essential in order to increase the recording density of hard disk drives (HDDs). We therefore developed a piggy-back actuator that generates a 1.4-mu m displacement at 5 V. This displacement is twice as large as that of usual piggy-back actuators. This actuator satisfies all requirements for HDDs including track density of 30 kilotracks per inch (kTPI). It will help us attain the low power consumption add high performance HDDs.
