Abstract
The floating clearance between the floating head slider and the disk of large capacity magnetic disk files is becoming smaller and smaller, the present values being from 0.3 to 0.5 μm. To ensure reliability, dynamic characteristics of the slider subjected to disk vibration or run out must be predicted accurately. Finite difference methods or Divergence Formulation Methods have heretofore been used to obtain the dynamic characteristics of sliders, but difficulties have been met in treating complex shaped sliders. In the present paper, the finite element method has been used. The calculated results agreed with those obtained by the above mentioned conventional methods. They agreed with the experimental results obtained using a taper flat type slider with yaw angle. Furthermore, the dynamic characteristics of a grooved slider and a negative pressure inducing slider have been predicted by this calculation method. The present methods are so formulated to include the calculations of both the static and dynamic characteristics.
