Abstract
The dynamic behaviour of the coercive force of particulate recording media is investigated theoretically. It is shown that as regards the value of Hc the field sweep is equivalent to an effective time determined partially by the particle volume. This is in agreement with an empirical relation arising from recent experimental data.Keywords
