Paper Abstract

Optical near-field recording with a super-resolution near- field structure (Super-RENS) records and retrieves small marks with dimensions beyond the diffraction limit. A thin layer of an antimony (Sb) film, added to the usual phase-change optical disk structure, is the key material of this technique. We investigated the nonlinear optical properties of the Sb film, especially the optical switching behavior in the stationary state using a nanosecond pulsed laser. Clear switching was observed under microscopic measurement. Time response of the optical switching properties were examined and found to show fast rise-up and slow decaying times.
