Although the mathematical model of a tape travelling over a cylinder foil bearing has been shown experimentally to be valid for a closely similar physical model, its application to predict separation between a tape and a magnetic head shows large discrepancies. In this work, a modified model of a foil bearing, taking into account some details of the particular geometry of magnetic heads, is used to predict separation. As a result, the gap between theory and experiment is narrowed down considerably. Author
