Magnetically induced super resolution in a magneto-optical disk



Research News: A tenfold increase in the storage density of magneto-optical media could be achieved through combining the use of a short wavelength laser and the application of a new detection technique known as magnetically induced super resolution. The effective spot size of the readout laser is reduced by passing the light through a magnetically induced mask (see figure) meaning that the information can be stored closer together on the disk.
