Abstract
A method for manufacturing an head gimbal assembly (HGA) according to the present invention is comprised of: a step for preparing a thin film piezoelectric actuator including a first piezoelectric laminate having a first piezoelectric layer, and a second piezoelectric laminate having a second piezoelectric layer; a step for preparing a suspension; a fixing step for fixing the thin film piezoelectric actuator to the suspension; a first repolarization treatment step for performing repolarization treatment to the first piezoelectric layer after the fixing step; and a second repolarization treatment step for performing repolarization treatment to the second piezoelectric layer after the fixing step.
