A Simplified Hysteresis-Loop Model of the AC-Biased Magnetic Recording Process

The model described in the paper is based on the assumption that the remanence of a magnetic material exposed to a series of field maxima of alternating sign, can be calculated as the superposition of the magnetizations, brought about by the successive maxima. Using a straight line approximation for the magnetization vs. field function, results in a theoretical recording model free of material-induced losses and distortion. By this model the influence of the recording geometry on the recorded signal smplitude and waveform can be examined. Recording, demagnetization, wavelength dependent harmonic distortion and phase shift data, calculated by computer, are displayed, and the limitations of this particular model, and those of the so-called 'classical' recording models are compared and discussed.
