<p>PLATED MAGNETIC RECORDING MATERIAL AND PROCESS FOR MAKING SAME Plated magnetic recording material, such as magnetic tape, composed of a thin layer of ferromagnetic metal and a base film layer are made by plating a passivated smooth continuous surface such as the surface of a cylindrical mandrel or an endless belt with a plate of ferromagnetic metal, applying the base film layer to the plated surface, and stripping the resulting laminated composite from the surface. The smoothness of the surface of the ferromagnetic metal layer depends on the smoothness of the continuous surface rather than on the smoothness of the surface of the base film stock.</p> |
