Abstract :
Master equation formalism is employed to describe the effect of a recording head on an initially demagnetized particulate medium. It is found that transition noise and transition shift along the track are inversely correlated and that large transition noise is found to be associated with high recording frequencies, low recording temperatures (large particles) and particle misalignment. Interparticle coupling is discussed
