A system for loading and unloading of magnetic heads mounted on self-loading air bearing sliders is controlled by a layer of Ni-Ti alloy "memory wire". The suspensions 1 are designed to produce a force to unload the slider 2 from the disk (not shown) as the disk slows to a predetermined speed, and the self-loading slider 2 is designed to provide a loading force of sufficient magnitude to hold the slider at the selected flying height over the disk and counteract the suspension force loading while the disk is at its operating rotational speed. The load/unload mechanism comprises a flat ring 3 that is positioned between the upper and lower suspensions 1 so that a change in the shape of the ring 3 from a thin oval shape to a more rounded oval shape causes the slider 2 to be moved in close proximity to the disk.
