Abstract :
The head/tape interface for a helical scanner is simulated using finite element methods in conjunction with a two-stage zooming technique. The head/tape spacing is investigated as a function of velocity and tension as well as surface roughness of the tape. Contact pressure is calculated using experimentally determined parabolic asperity compliance curves. The results show that head/tape spacing is limited by surface roughness
