Three dimensional numerical analysis of a spherical foil bearing used in a rotating head recording device is presented. Reynolds equation is solved simultaneously with the representative Green function of plane or cylindrical foil deformation, which includes bending stiffness. Calculated pressure, spacing and foil deformation are illustrated and typical trends are discussed for small bearing penetration. The calculated results are found to be in good agreement with the experimental results under submicron spacing conditions.
