Abstract
Metal particulate tape is one of the most advanced tape media to offer excellent performance at high recording densities. An accurate micromagnetic model of metal particulate tape has been developed to analyze the magnetic properties of MP tapes. Both particle size distribution and orientation distibution are included in this model and magnetostatic interactions among particles are accurately calculated with the shape of ellipsolds. A partial mean field approximation applied in the calculation is approved to be effective by M-H loop anaiysis.
