Abstract
The dynamic response of a tape caused by an impact load is analytically modeled. The solution is obtained using modal expansion techniques. Results from examples illustrate the model's potential for design of the head-tape interface in magnetic recording. Parametric changes may be assessed under dynamic loading conditions for the localization of deflection and the dispersion of energy. An interesting result is that desirable, near-steady conditions may be achieved even without the benefit of an explicit damping mechanism. Numerical simulations indicate that the transient displacements decrease when the tape thickness is reduced, when the damping coefficient is increased, when the foundation stiffness is increased, when the point of application of the load is moved away from the free edges, and when the tension is increased. Parameter studies showed that the stiffness k was very important to the dynamic response. >
