Head gimbal assembly with piezoelectric microactuator |
摘要 |
A piezoelectric device comprises an integral body of piezoelectric material having a length and width greater than its thickness; wherein the device further includes, in contact with the body, respective pairs of electrodes, wherein the electrodes of each pair are opposed in the thickness direction, wherein the body deflects along said transverse direction when a voltage is applied to the electrode pair. The present invention further provisdes a disk drive suspension and a head gimbal assembly.
