Title: Apparatus for electro deposition of magnetically anisotropic metallic recording films

Abstract: Described are methods and apparatus for plating a thin magnetic recording film having "uniaxial anistropy" wherein a magnetic plating head and plating anode are disposed in cooperative relation adjacent the substrate-cathode to comprise a "plating transducer" which may be translated relative to the substrate so as to sweep the magnetic-gap-field across the substrate to align the plated material as it is deposited. Such an arrangement is especially apt for pre-aligning a film plated along the annular recording tracks of a disk substrate, the disk being rotated past the transducer-anode array which is aligned radially across the disk's recording face.
