Paper Abstract

A new proposal for near-field data storage and the basic experiment under a high speed disk rotation are described. Using the thermally nonlinear property of an Antimony thin film and an intermediate layer of SiN with a thickness of 20 nm, less than 100 nm sized marks were recorded and retrieved in an optical phase change film beyond the diffraction limit, with a wavelength of 680nm and a lens NA of 0.6.
