... air bearing gas bearing iterative method Simulation of an air- or gas-lubricated bearing requires the solution of compressible-fluid Reynolds equation. Due to the lack of analytical solution Reynolds equation is usually solved numerically after the equation is discretized. The discretized...

...Puneet Bhargava; David B. Bogy Prediction of the steady state flying height and attitude of air-bearing sliders in hard disk drives via simulations is the basis of their design process. Over the past few years air-bearing surfaces have become increasingly complex incorporating deep etches and steep...

...Shuyu Zhang; Sung-Chang Lee; Dongman Kim; Joerg Ferber; Brian Strom; George Tyndall Thermomechanical actuation (TMA) at the transducer region of the air bearing surface (ABS) protrudes from the transducer toward the recording media. This actuation induces a change in the air bearing pressure...

... going through the trailing pad of an air bearing slider cause severe contact forces on the slider and generate large heat sources. The frictional heating study shows that the temperature around the magnetoresistive head increases to about 5 ° C for a single 200 nm particle passing through the trailing...

...Shuyu Zhang; Brian Strom; Sung-Chang Lee; George Tyndall For a hard disk drive operating in a humid environment, the water vapor in the slider’s air bearing is typically compressed beyond its saturation vapor pressure, causing the vapor to condense. Consequently, the air bearing pressure decreases...

...Shuyu Zhang; Brian D. Strom A new method is introduced for predicting particle and liquid droplet contamination on an air bearing surface. The method primarily relies on the analysis of flow patterns nearest the air bearing surface, restricted to two dimensions. In addition, a mathematical model...

...Hong Zhu; David B. Bogy This paper addresses the effects of pitch static attitude (PSA) and roll static attitude (RSA) on air bearing slider steady performance, especially for ultralow flying height sliders. We performed simulations for three different low flying sliders with flying heights (FHs...
