This Thesis reported study characteristics of self acting air bearing head and rigid disk in magnetic storage system .In this study, incompressible flow, compressible flow and molecular slip flow, have been investigated. In order to consider the plane wedge type slider, which compose of two rails to pressurize the air. The design of ultra low clearance between the slider head and rigid disk interface is to achieve high data storage density. Two degree of freedom motion of slider head; translation perpendicular to the disk surface and rotation around the transverse axis were simplified in this investigation. Numerical solution of the two dimensional nonlinear modified Reynolds equation has been formulated by using variable grid size .A numerical scheme base on the finite difference technique and linearization and iteration method have been used to simulate steady state flying characteristic.
