Experimental testing of the average Preisach model of hysteresis

The authors report the results of extensive experimental testing of the average Preisach model of hysteresis. This testing has been performed for the following magnetic tape materials: Ampex-641, Ampex-797, Ampex-D1, TDK-VHS, Maxell-Beta, and Memorex-3480. Experimental results have revealed the consistent and remarkable accuracy of the average model. It is believed that this accuracy is related to the fact that the average model provides the far-reaching generalization of the congruency property of the classical Preisach model. Actually, this generalization goes much further than in the cases of the input-dependent or restricted Preisach models, although the average model needs the same experimental data for its identification as the two aforementioned models
