Abstract :
A vector Preisach hysteresis model, taking into account the out-of-plane anisotropy of metal evaporated recording tapes was developed and implemented in a 2D finite element software, so as to model the writing process on these media. The shape of the computed transition is clearly modified by anisotropy. Computed and experimental readback voltages were compared and a very close agreement was found, which can not be achieved by using only a scalar model
