Resumen
The article focuses on combining optical techniques and magnetic storage media. Magneto-optical (MO) technology will likely be used in magnetic drives to improve data density. Computer users tend to take for granted the existence of magnetic and optical memory devices that offer breathtaking data-storage capacity with extremely high reliability at very low cost. The technological wonders of these rugged devices routinely escape users' notice, because the internal functioning of disk drives is hidden from view. Nevertheless, magnetic and optical drives are arguably among the world's most sophisticated electromechanical devices. Equally astonishing is the rapid advance of this technology far outpacing the highly visible technology sectors of semiconductor electronics and computer software. Two of the most striking physical characteristics MO technology are the exponential growth of the data-storage density in commercial products and the mechanical performance of recording heads following a track of recorded information on the medium.
