High-density recording four times that of a current DVD-RAM has been achieved by applying Domain Wall Displacement Detection (DWDD) technology using a conventional optical head which has the same wavelength of 660 nm and NA of 0.6 as the DVD head. It

We developed a negative-type photoresist of WOx film and obtained a low noise groove. We also confirmed a feasibility of the transmissive stamper using the WOx film for multi-layer discs. Keywords: phase transition mastering, stamper, multi-layer, bl

In this study, a commercial BD (Blu-ray disc) and BD optics (blue laser and NA0.85) were used for multilevel recording. The goal is to double both the present capacity and data transfer rate. To achieve this, it is necessary to overcome severe inter-
