ABSTRACT
It is anticipated that magnetic data storage will exceed a density of
1.5 x 10^(09) bits/sq. cm. (1 x10^(10) bits/sq. in.) within the next 10 years,
and quite possibly achieve even higher areal densities. However, with
the invention of new scanning probe microscopes, it is possible
that new technologies will emerge which can achieve higher data
densities. These techniques have demonstrated the ability to manipulate
matter on the atomic scale, and thus offer the potential of extremely
high data densities. In this talk, I will review some of these new
scientific techniques, including scanning tunneling, atomic force,
and near-field optical microscopes, with particular attention on their
application for data storage. The challenges in advancing these techniques
from scientific tools to real data storage technologies will be highlighted.
