Abstract :
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.
