摘要

The study of ultra thin gas film bearings has become of great interest in recent years. The prime motivation comes from the computer magnetic disk recording industry where higher recording density can be achieved if the read/write element which is attached to the taper-flat slider can be maintained at a closer spacing over the magnetic disk rotating at a high speed. The slider/disk separation is so thin that the flow can be considered as a lubricated flow. This is commonly described using the Reynolds equation which is used to compute the pressure and then the hydrodynamic lift which has to balance the weight of the slider. For incompressible fluids like water or oil, the Reynolds equation is a linear elliptic type [3]. For compressible fluid-like air it becomes highly nonlinear and has been a subject of many mechanical studies [4,7,9,11].
