| | Effects of Slider-Driven Piezo-Microactuator Placements and Profiles on HGA Sway Mode | | Authors: | J.P. Yang and S.X. Chen | | Affilation: | National University of Singapore, U.S.A. | | Pages: | 326 - 329 | | Keywords: | piezo-microactuator, head gimbal assembly, hard disk drive, FEM, vibration | | Abstract: | With areal recording density of hard disk drives (HDD) historically growing at an average of 60% per year, it is becoming increasingly more difficult to maintain the precise positioning required of the ever-smaller GMR heads to read and write data. It is predicted that 100 Gb/in 2 HDD areal density would be probably delivered by 2003. To reach such high track densities, the lower mechanical disturbances and higher servo-control bandwidth is required. The dual-stage servo system has been considered as the most promising solution. The motivation of this work is to analyze the effects of the slider-driven micro-actuator placements and profiles on head gimbal assembly (HGA) microactuator sway mode. Results showed that the sway mode frequency was obviously increased by selecting micro-actuator placements and its profiles, optimally. |  | View paper | | ISBN: | 0-9708275-0-4 |
