This paper addresses the effects of pitch static attitude (PSA) and roll static attitude (RSA) on air bearing slider steady performance, especially for ultra-low flying height sliders. We performed simulations for three different low flying sliders with flying heights (FH) of 7nm, 5nm and 3.5nm using the static simulator code of the Computer Mechanics Laboratory (CML). We found that PSA and RSA have quite significant effects on the steady performance of these air bearing slider designs, and the effect is more important the smaller the size and the lower the FH of the slider. We also investigated the effects of suspension stiffness on the air bearing sliders’ flying attitude (pitch and roll) and found that these effects are similar to those of PSA and RSA.
