...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...

...Yanhui Yuan; Shao Wang A five-degree-of-freedom model was developed for the analysis of the off-track motion of the magnetic head slider in a hard disk drive. The air bearing was integrated into the dynamic system by combining its stiffness and damping matrices with those of the suspension...

...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...

..., and their consequent effects. Particle and lubricant contamination on the ABS have been a serious problem affecting the reliability of hard disk drives since the industry’s inception. To investigate the mechanism of the contamination and solutions to it, many people did research in various approaches...

...P. Bhargava; D. B. Bogy As nontraditional applications of hard disk drives emerge, their mechanical robustness during the operating state is of greater concern. Over the past few years, there has been an increasing application of small form factor ( 1 in . and smaller) hard disk drives in portable...

...Qinghua Zeng; Fu-Ying Huang Load∕unload (L∕UL) technology has been widely applied in hard disk drives for a long period of time. One main promise of this technology compared with the contact start-stop (CSS) technology was no damage from the friction and stiction between sliders and disks during...

...Takuji Kobayashi; Hiroshi Yabe A numerical model has been developed to analyze both static and dynamic characteristics of a coupled porous journal and thrust bearing system that is used to support a rotating shaft in a magnetic hard disk drive. The analyzed system is composed of a porous sleeve...
