Abstract:A thin MP tape is modeled to study the overwrite behavior as a function of increasing head field. For the simulation we use a moving-Preisach and Stoner-Wohlfarth hysteresis model which is implemented in a numerical recording model. A measurement at the optimum current of the overwrite ratio (OWR) shows a perfect reproduction of its value in the simulation. A layer-by-layer depth analysis is performed to investigate the origin of the residual signal. The model can also explain the decreasing trend of the OWR versus the head field.
