A brief discussion of the differences in two generalized slope models
suitable for modeling metal evaporated tape is presented. The inclusio
n of idealized correlations between the sublayers in one of the models
is proposed as an explanation for the differences in the predictions
of these models. The correlations appear to mimic the effect of strong
magnetic interactions that are thought to be present along the obliqu
e easy-axis direction in metal evaporated (ME) tapes.
