Abstract

A magnetic recording head includes a piezoelectric actuator for controlling head-media spacing. A method for making the magnetic recording head including a piezoelectric actuator includes the steps of: providing a source wafer on which to fabricate the piezoelectric actuator; providing a target wafer; fabricating the piezoelectric actuator on the source wafer; releasing the piezoelectric actuator from the source wafer; and placing the piezoelectric actuator on the target wafer.
