Abstract
Device for recording data comprising microdots with free ends forming a convex surface and method for the production thereof The data recording device comprises a storage medium arranged facing a two dimensional array of microdots, of nanometric dimensions, formed directly on a substrate. An electronic circuit for addressing and controlling the microdots is integrated in the substrate. The microdots and/or substrate are shaped in such a way that the set of free ends of the microdots defines a convex surface, which enables a contact to be ensured in all cases between each of the microdots and the corresponding storage medium. The radius of curvature of the surface convex is preferably comprised between 1 m and 5 m.
