Abstract

The linear density of an optical disk is limited within the cut-off spatial frequency which is determined by the spot size of a focused beam. If the spot size is effectively reduced by using new technology, a remarkable improvement in the density could be achieved. Still more, combining with the technology of shorter wavelength laser could result in more than one order development.
