Contamination of the head-disk interface (HDI) is known to degrade the performance of the disk drive. Through decades of ongoing improvements the level of airborne chemical contamination, although measurable, is extremely low in today's disk drives. Yet, exposure to aggressive environments can still produce droplets of liquid contamination at the HDI. This can cause increased startup friction or "stiction"...
The development of a state-of-the-art UHV surface science instrument is described. It has been built to study the relationship between the atomic structure and the magnetic anisotropy of ultrathin magnetic films and their interfaces. The unique aspect of this instrument is the particular combination of several in-situ surface techniques, MEIS and LEED for detailed atomic structural determination,...
