Abstract
A flexure is provided with a main body on which a wire for energizing a head slider is disposed. Head slider is mounted at the front end of the flexure. Two piezoelectric layer units, each including layered piezoelectric elements, are disposed so that two of the units sandwich a line that extends from head slider to a base portion of an arm member. A voltage can be applied individually to each of the piezoelectric elements. The shape of the piezoelectric layer units are changed by adjusting the voltage applied to each of the piezoelectric elements, thereby moving head slider freely.
