The diffraction from two-dimensional magneto-optical marks has been calculated using the plane wave expansion method and the Fourier modal method. The modulation transfer function (MTF) in near field magneto-optical recording has been simulated for the first time on the basis of the strict vector diffraction theory. The simulated result proved that the magneto-optical signal is reduced by only 3 dB at a spatial frequency of NA/lambda, for an air gap of 50 nm between a solid immersion lens with an effective numerical aperture (NA) of 1.5 and a magneto-optical disk surface.
