A HGA of the invention includes a slider, a micro-actuator for adjusting the position of the slider; a suspension to load the slider and the micro-actuator; and a vibration canceller interposed between the micro-actuator and the suspension. The micro-actuator includes a first base-part plate, a pair of actuator side arms extending from the first base-part plate in a first direction, and at least one of side arms has a piezoelectric element thereon. The vibration canceller includes a second base-part plate to connect with the micro-actuator and the suspension; and at least one canceling arm extending from the second base-part plate in the first direction or in a second direction, wherein at least one of canceling arms has a piezoelectric element thereon. The invention also discloses a disk drive with the vibration canceller.
