Brusche, J.H. (author), Segal, A. (author), Vuik, C. (author), Urbach, H.P. (author)In optical rewritable recording media, such as the Blu-ray Disc, amorphous marks are formed on a crystalline background of a phase-change layer, by means of short, high power laser pulses. In order to improve this data storage concept, it is of great importance to understand the mark formation process. Therefore, a rigorous numerical model is...conference paper 2006

Brusche, J.H. (author), Segal, A. (author), Urbach, H.P. (author)The finite-element method is applied to model phase-change recording in a grooved recording stack. A rigorous model for the scattering of a three-dimensional focused spot by a one-dimensional periodic grating is used to determine the absorbed light in a three-dimensional region inside the phase-change layer. The optical model is combined with a...journal article 2005
