Abstract

This paper describes a theoretical model for the prediction of the spacing profile between a flexible magnetic tape tensioned around a rotating drum and a protruding head mounted on the drum. The analysis is based on the coupled equations controlling the elastic deformation of the tape and the hydrodynamic pressure of the gas film. Some results are presented for a cylindrical head.
