As we approach the turn of the century, the demand for storage is rapi
dly increasing, fueled by multimedia and its associated applications.
Hard disk drive (HDD) manufacturers continue to respond by chasing the
areal density curve to provide higher capacity and higher performance
disk drives. The required technology changes are expected to aggravat
e performance and reliability problems, such as stiction, associated w
ith organic contamination; thermal asperities, associated with particu
late contamination; and corrosion, associated with ionic contamination
. Anticipation and proactive resolution of chemical integration and co
ntamination control problems are key to the successful development and
manufacturing of advanced HDDs. In this paper, types and sources of c
ontamination that can impact HDD performance are described; various co
ntamination-related problems are reviewed; and a methodology by which
successful chemical integration in the hard disk drive business can be
accomplished is outlined.
