A HGA of the present invention includes a slider; a micro-actuator comprising two thin film PZT pieces to define a notch; a suspension to load the slider and the micro-actuator. The suspension comprises: a flexure having an actuator loading portion with a slot corresponding to the notch of the micro-actuator, and a slider-loading portion to partially hold the slider; and a load beam having a first dimple to support the flexure at a position thereof corresponding to a central area of the slider, and a second dimple extending through both the slot of the flexure and the notch defined by the micro-actuator and toward an leading edge end portion of the slider to form a gap between the slider and the second dimple. The invention also discloses a disk drive unit having the improved HGA.
