A data storage device includes a head suspension assembly having an attached airfoil. The airfoil is coupled to an active (i.e., movable) element that responds to signals from height control circuitry. A method of controlling a height of an air bearing surface includes positioning a suspension assembly having an airfoil and an air bearing disk head over a surface of a rotating data storage disk. A position (e.g., an angle) of the airfoil can then be dynamically altered to change a distance of the disk head perpendicular to the surface of the disk.
