Abstract
A previously developed simulation of a thin film recording medium has been extended to include evaluation of noise characteristics. The reco rding medium has been taken through the dc demagnetisation curve and n oise characteristics at various remanent states computed for three deg rees of inter-granular exchange coupling. The IRM curves were also com puted, to allow the computation of the delta M(H) curves. The remanenc e curves and noise curves were in good agreement with experiment. It w as found that the peak in the noise curves for all three degrees of ex change coupling occurred at approximately the same field as the maximu m slope in the delta M(H) curves.
