Abstract

An improved concept of the advanced SIL and its compensation OL of composite effective NA over 1.7 has been designed and manufactured to achieve wider assembling tolerances, higher data capacities and better signal quality. Very clear readout signals were measured from a 25 GB BD-like ROM media with 3 um cover layer and the applying feasibility of the advanced SIL system in near field optical storage was confirmed. With this novel advanced SIL system and multilayer media concept, total capacity over 500 GB per disc was expected to be accomplished.
