A finite element 2D simulation of recorded magnetization on a slave medium with patterned thin films on a master medium was performed by solving the Poisson equation for the magnetic printing system. As a result, the following conclusions were drawn : (1) The printing field decreases drastically in the central region of two magnetic films as compared with that at the film edges. (2) When the printing field is weak, the magnetization in the central region cannot be switched under the printing field, and the output voltage waveform is severely distorted. (3) When the printing field is too strong, the peak of the output voltage waveform shifts in the film edge direction, although the magnetization can be switched completely. (4) The optimum printing field depends strongly on the distance between the films.
