Abstract
The head/tape interface for a helical scanner is simulated using finit e element methods in conjunction with a two-stage zooming technique. T he head/tape spacing is nvestigated as a function of velocity and tens ion as well as surface roughness of the tape. Contact pressure is calc ulated using experimentally determined parabolic asperity compliance c urves. The results show that head/tape spacing is limited by surface r oughness.
