Abstract
A method of and apparatus for producing magnetic media are disclosed. Magnetic particles in a magnetic layer are oriented under the influence of a magnetic field positioned on one side of the layer and having its lines of flux extending in a direction which is generally perpendicular to the magnetic layer, while the latter is cured by being subjected to electron beams incident on an opposite side of the layer, whereby the particles are fixed in the desired orientation.
