[18p-C104-4] Thin film piezoelectric micro-actuator for HDD application

〇Naoto Matono1, Garry Topacio1, Michael Wong1 (1.SAE Magnetics)

Keywords:HDD, Piezoelectric, actuator

Advancing areal density requires a challenging combination of technology. One of these challenges is the precise positioning of magnetic heads. Dual stage actuator (DSA) enables better head-positioning accuracy. Thin film piezoelectric actuator has been practical in HDD application to realize higher recording density.
