Dynamic Characteristics of Floating Head Mechanism

Abstract

We investigated the dynamic characteristics of air floating head mechanism for magnetic storage drum. According to the results of numerical calculation on small vibrations of a slider near its equilibrium point, the smaller the clearance is, the larger the stiffness and coefficient of viscosity of air film are, and the larger the curvature is than that of the drum, the better the characteristics will be. Even in large vibrations, the smaller the clearance is, the higher will be the degree of stabilty. These were proved by experiments.
