The data recording device comprises a network of carbon nanotubes formed
on a flat substrate and constituting microtips operating in conjunction
with a substantially flat storage medium. The carbon nanotubes are
initially inclined by a predetermined angle comprised between 5.degree.
and 40.degree. with respect to the plane of the substrate. The nanotubes
flex when they come into contact with the storage medium, parallel to the
substrate. The substrate preferably comprises a raised structure designed
to act as support for the free ends of the nanotubes to bear on.
