ABSTRACT:
Information stored in a thin polymer layer is read out in a process wherein information introduced into a thin polymer layer on a metallic or semiconductor layer by electromagnetic or particle rays which produce a permanent change in the properties of the polymer layer in the irradiated areas is read out using surface plasmons.
