Abstract

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.
