Abstract
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° and 40° 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.
