...Norio Tagawa, Professor; David B. Bogy, Professor This paper describes the air film dynamics for micro-textured flying head slider bearings in magnetic hard disk drives and it discusses their ability to increase the air film damping. In order to study the effects of micro-textures on air film...

...Sinan Mu¨ftu¨; M. Cengiz Altan A model for analyzing the interfacial conditions of a porous web moving over a cylindrical rigid guide is presented. This problem is different from the classical foil bearing problem due to the fact that the air can diffuse through the porous web itself...

...Luoyi Tao, Research Associate; Sergio Diaz, Graduate Student; Luis San Andre´s, Associate Professor; K. R. Rajagopal, Professor Rotor-bearing systems supported on squeeze film dampers (SFDs) show large amplitude vibratory motions when traversing critical speeds. At these operating conditions air...

...Weidong Huang; David B. Bogy, Fellow ASME In solving the slider air bearing problem, both the Molecular Gas-film Lubrication (MGL) model and the Direct Simulation Monte Carlo (DSMC) model require the accommodation coefficient as input. The accommodation coefficient represents the fraction...
