Researchers at the Universidad Autónoma de Barcelona, Institute of Ion Beam Physics and Materials Research and the Centro de Investigación en Nanociencia y Nanotecnología CIN2 have developed a procedure for making a quick, cheap and controlled entirely flat magnetic means shaped by nanomagnets. By this procedure they can record on the surface of a non-magnetic material, ferromagnetic small areas that will hardly alter the topography of the lithographic material. 

The result of this research could lead to new basic units of information in computer hard disks, greatly increasing the density memory.
