Popis:	Large capacity is a strong requirement for the next generation of magneto-optical disks in order to man-age huge amount of data such as digital images. We reported that superresolution can be realized by using anexchange-coupled multilayer disk in 199 1. This novel technology is called Magnetically Induced Super Resolu-tion (MSR) and it more than doubles the readout resolution limit of the conventional optical disk system with-out shortening the laser wavelength or increasing the numerical aperture (NA) of the optical lens 1),2)•
