Abstract
A magnetic data transducing head slider is provided with a transversely extended crossbar or other barrier near the leading edge. The barrier is deposited onto the air bearing surface of the slider using photolithographic techniques that enable precise determination of the barrier dimensions and the barrier set-back from the leading edge. The barrier set-back, width and thickness can be selected to control the transducer flying height and the pitch of the slider relative to the data recording surface of a magnetic disk when the slider is aerodynamically supported relative to the disk. The barrier also acts as a shield to minimize particulate contamination.
