Paper Abstract

High density rewritable recording and readout characteristics with a solid immersion lens (SIL)-based near-field recording (NFR) are investigated. Substrates for high density are prepared using a phase transition mastering technique. Cover-layers with different refractive index for different effective numerical apertures in the SIL optics are coated on rewritable NFR discs for cover-layer incident near-field recording configuration. Two different effective numerical apertures are chosen between 1.45 and 1.85 to cope with about 70 GB and more than 100 GB per disc, respectively. The performance readout signals is investigated and compared in terms of increasing recording densities with reducing track pitch.
