Abstract

A phase-change optical disc was observed using a reflection-mode scattering-type scanning near-field optical microscope (RS-SNOM). In an a.c.-mode SNOM image, the 1 . 2 mu m x 0 . 6 mu m recording marks were successfully observed although the data were recorded on the groove. in contrast, no recording marks could be resolved in a d.c.-mode SNOM image. These results are ingood agreement with those from a numerical simulation using the finite difference time domain method. The resolution was better than 100 nm with a,c.-mode SNOM operation and the results indicate that recording marks in phase-change optical media can be directly observed with the RS-SNOM.
