Abstract :
In this work, the effect of long-wavelength nonuniform lube distribution and lube de-wetting on head-disk dynamics is investigated by using disks with controlled within-disk nonuniformity in lubricant film thickness. Complex slider responses were observed, which were sensitive to lubricant film thickness and the extent of de-wetting. The effect of slider-assisted lubricant redistribution was also observed
