A Simulation Model for Two Dimensional Recording on Continuous Granular Media

In this paper, we present analyses of the media response to the write field with the recorded bits each of which involves a small number of grains. Our focus is on the development of a model that can be used to generate speedily the recorded patterns on continuous granular media. A two-dimensional Fourier analysis method is then used to construct the recorded patterns corresponding to given bit stream of write signals for signal to noise ratio evaluation.
