摘要
Using a silver oxide thin film of a non-magnetic mask laver, the magneto-optical (MO) recording signals were enhanced by surface plasmon. A resolution of less than 170 Dun was achieved by the near-field coupling between a light-scattering center generated in the AgOx film and the light polarization of MO marks. The electrical field intensity was also confirmed by a computer-simulation. Optimization of the disk structure and materials, and the effects of readout power were investigated.
