摘要：

The equations describing the steady-state flying height of magnetic tape over a recording head are solved using a new algorithm that incorporates a linearized approximation of air bearing stiffness into the tape equation. As in previous investigations, the one-dimensional (infinitely wide) equations include compressibility and slip flow in the air bearing as well as tension, momentum, and flexural rigidity in the tape. The stiffness coupling between the equations allows simulation of complicated head geometries and reduces the computational effort required to determine the steady-state flying height by more than an order of magnitude compared to previous methods which are based on the time dependant equations. Two example problems from the literature are presented, both of which were solved on a personal computer in under one minute. © 1990 IEEE
