The magnetic tape is deformed in cross-section from straight to curved and then back from curved to straight. To prevent kinks and folds in the magnetic tape as a result of this deformation, tape curving means exert pressure on the magnetic tape to increase the local degree of curvature of the magnetic tape. As a result, differences in local membrane stress in the tape cross-section at the location of the rotary magnetic head paths are reduced. | |
