Abstract
The two sided magnetic recording tape consists of a standard film substrate to which a coating of magnetic recording materials is applied, on both sides thereof. In order to reduce the effect of magnetic print through and contact recording, the particles or films that are applied to both sides of the substrate are oriented during manufacture in differing magnetic orientations that are angularly displaced with respect to each other, either coplanar or non-coplanar on the recording surface of the magnetic tape.
