Abstract
Air bearing simulation and a novel laser heterodyne interferometer are used to investigate the air bearing features that may be effective in lowering takeoff velocity and thus reducing sliding wear. Slider dyna mics, takeoff velocity and pitch angle of the slider during the Initia l stages are considered. The parameters studied include taper angle an d load placement. Correlation between theory and experiment In the sub 0.25 mu m range is shown and discussed.
