A device (198) for lapping a bar (10) of the type which carries a plurality of sliders used in magnetic storage systems includes first, second, and third actuators (220, 222, 224) adapted to couple to the bar (10), and impart a first, second, and third controllable force in response to a first, second, and third control signal, respectively. An arm (204) couples to the first, second, and third actuators and applies a lapping force to the bar (10) which presses the bar (10) against a lapping surface (208) thereby causing material to be removed from the bar (10). A controller (262) provides the first, second, and third control signals to the first, second, and third actuators (220, 222, 224), respectively. To impart a plurality of forces onto the bar (10). The actuators (220, 222, 224) are controlled to obtain a desired profile of the bar (10) and to obtain a desired distribution of the lapping force across the profile of the bar (10).
