Abstract
An improved method of making a magnetic recording material comprises providing a ferromagnetic metal thin layer which has uniaxial anisotropy in any direction on a web by means of plating. A plating solution is jetted onto the web through holes in a conveying pipe set in a plating bath. The web is then moved from the vicinity of the conveying pipe by the spouting force of the plating solution, and then conveyed along a helical path about the conveying pipe without contacting the surface of conveying pipe. Plating occurs while applying a magnetic field to the web.
