Comprehensive Model For The Simulation Of The Recording Performance Of Optical Storage Media

The thermal evolution in thin-film multilayer Optical Storage Media (OSM), upon exposure to a writing pulse, depends upon recording system parameters and both optical and thermal properties of the OSM. This paper presents a model of the process that accounts for the distribution of heat generated in the absorbing layers and both axial and transverse thermal diffusion. Once the physical characteristics of a mark generated in the OSM have been predicted, readback performance is modeled under various detection schemes and drive parameters.
