Simulation of Head-Disk Collisions in Magnetic Recording

Numerical simulation programs that adopt the methods described in (1), (2), (3) are widely used in the Magnetic Recording industry to study head-disk interaction, but they are not capable of accommodating head-disk contacts. In the present work, a simulation tool is developed and applied to analyze the dynamics of a slider flying under the influence of hydrodynamic forces and subject to intermittent contact with rapidly moving disk surface defects such as localized asperities.
