Head actuator driven by piezoelectric element
摘要:
A head actuator mechanism characterized has a head that records and reproduces data; a suspension that holds the head; a support arm; a drive means for moving the support arm; a coupling section for coupling the support arm and the suspension together in such a way that the head can move relatively to the support arm; and at least one piezoelectric element for coupling the support arm and the suspension together to move the head relatively to the support arm for fine tuning, the piezoelectric element being fixed to the support arm and suspension at both ends.
