Method for preparing magnetic recording media

摘要

A method for preparing a magnetic recording medium comprising a non-magnetic support having coated thereon a magnetic layer containing plate-shaped ferromagnetic fine particles oriented perpendicular to a plane of the surface of the support, the process comprising the steps of: coating the non-magnetic support with a coating composition wherein ferromagnetic fine particles are dispersed in a solution comprised of a compound polymerizable by radiation with electron beams and a solvent, said particles being plate-shaped and having an axis of easy magnetization perpendicular to a plane of the plate-shaped particles; orienting the ferromagnetic fine particles perpendicular to the surface of support while the coating composition is undried; radiating the composition with electron beams; and drying the composition by removing the solvent.
