Paper Abstract

Organic material with pronounced thermochromism is used as a mask layer in a phase change optical disk. The thermochromic material exhibits significant change in optical properties at increased temperatures as well as fast response upon pulsed laser irradiation. Recording and retrieving signals from marks smaller than that of the diffraction limit is investigated under high speed disk rotation.
