In flying magnetic heads over rotating disks, it is often advantageous to have an increasing load force as the air bearing distance increases. For instance, it would be advantageous to have a very light load when the disk is stationary and the slider is in contact with the disk and a relatively higher load when the disk is rotating at full rotational speed. The small load insures that the head contacts the disk in a desired pitch and roll attitude and does not fly free without a load when the air bearing is depleted.
