A storage device includes a storage medium, a controller and a read/write
head. The storage medium includes a substrate with a plurality of
nano-structures arranged in an ordered pattern on a surface of the
substrate. The controller is coupled to the storage medium. The
controller has a read structure that extends over the substrate and a
positioner adapted to adjust a position of the read structure relative to
the substrate. The read/write head is mounted on the read structure and
positioned over the substrate during operation. The read/write head is
adapted to read and to write information to and from the plurality of
nano-structures.
