Since many of the newer disk drive products incorporate load/unload to avoid starting and stopping on the disk surface, a new low-velocity accelerated life test was developed to simulate the tribology at ultra-low flying height with asperity contacts

The one-dimensional diffusion equation is solved numerically to calculate the spreading profile of a molecularly-thin liquid on a solid surface. The thickness-dependent diffusion coefficient of the liquid is derived from the thickness dependence of t

Frictional hysteresis loops are measured with a pico-slider on typical desktop media to illustrate the bridged state with a chemisorbed perfluoropolyether lubricant. Our new molecular adhesion model calculates the mean spacing and bridge stiffness fr

In an earlier report, flyability failures due to siloxanes were investigated comparing disks with either Z-Dol or X-1P lubricant. On the Z-Dol disk, the head-disk interface failed at 47 h (h) and the slider accumulated silicon oxide smears, whereas t
