Readout Modeling of Super Resolution Disks

We describe 3-dimensional numerical simulations (performed using a finite-difference-time-domain modeling tool) of the readout of very small marks recorded on the data surface of an optical storage medium that incorporates a super resolution (SR) structure comprised of two dielectric thin films which encapsulate a thin AgOx film. We study how different types of light scattering objects, which are dynamically formed in the SR structure during readout of the recorded data surface, affect the characteristics of the reflected optical power modulation.
