Explained are the analytical method of contact status between magnetic heads and magnetic tapes, as well as the results of such analysis. The tape deformation is obtained in the form of influence coefficents "A_<ij>" created at a point "i" when a unit load is applied to a point "j". The contact status is clarified by adopting the theory of increments in which calculations are successively made while causing a head and a tape to gradually contact each other. The contact length upon the head differs depending on the values of the head radius, the tape tension, the tape rigidity and the degree of protrusion of heads. The actual measurement was achieved by utilizing the interference fringe pattern created between the head and the transparent tape. The experimental results are in close accord with numerical results.
