Slider posture effects on air bearing in heat assisted magnetic recording system

This digest reports the posture effects on the slider bearing of heat assisted magnetic recording (HAMR) with a direct simulation Monte Carlo (DSMC) method. The pressure distributions acted on the slider surface in a HAMR system with the presence of a heat spot on the disk or high slider temperature...

description	This digest reports the posture effects on the slider bearing of heat assisted magnetic recording (HAMR) with a direct simulation Monte Carlo (DSMC) method. The pressure distributions acted on the slider surface in a HAMR system with the presence of a heat spot on the disk or high slider temperature are investigated at different pitch angles. The simulation results show that the bearing pressure and force increase when the pitch angle increases. Furthermore, the smaller pitch angle increases the tendency of bearing force with the varying slider temperatures and makes the slider more sensitive to the slider temperature changes. However, it can help to reduce the effects of heat spot on the air bearing.
