A magnetic tape favorably employable for recording computer data, comprising a support web, a magnetic layer and a back-coat layer and having a thickness of 3 to 10 μm, should have a curl having a radius of curvature of greater than 10 mm in its longitudinal direction and a curl having a radius of curvature of greater than 40 mm in its width direction, wherein the curl in the width direction gives a convex surface on the side of the magnetic layer. |
