    摘要: According to an aspect of an embodiment, a method for manufacturing a magnetic head support having a piezoelectric device on a metal plate member comprises the steps of: providing a metal plate member; forming a piezoelectric layer of a piezoelectric material on the plate member at an elevated temperature; forming a first electrode layer of an electrical conducting material on the piezoelectric layer; and bending the metal plate member at a bending portion adjacent to the piezoelectric layer while the temperature is lowered from the elevated temperature after forming the piezoelectric layer.

    摘要: A micro displacement mechanism minutely displaces an object to be driven. The micro displacement mechanism includes a stationary part and an actuator fixed to the stationary part so as to rotatably support the object to be driven. The actuator includes a pair of piezoelectric actuators attached to opposite side surfaces of said object to be driven, respectively. The pair of piezoelectric actuators are arranged at point symmetric positions with respect to a center of gravity of the object to be driven.
