Query: Probe-based data storage   Probe-based data storage attracted many researchers from academia and
industry, resulting in unprecendeted high data-density demonstrations. This
topical review gives a comprehensive overview of the main contributions that
led to the major accomplishments in probe-based data storage. The most
investigated technologies are reviewed: topographic, phase-change, magnetic,
ferroelectric and atomic and molecular storage. Also, the positioning of probes
and recording media, the cantilever arrays and parallel readout of the arrays
of cantilevers are discussed. This overview serves two purposes. First, it
provides an overview for new researchers entering the field of probe storage,
as probe storage seems to be the only way to achieve data storage at atomic
densities. Secondly, there is an enormous wealth of invaluable findings that
can also be applied to many other fields of nanoscale research such as
probe-based nanolithography, 3D nanopatterning, solid-state memory technologies
and ultrafast probe microscopy.
