发明名称 MAGNETIC RECORDING MEDIUM WITH VERTICALLY ORIENTED MAGNETIC PARTICLES
摘要 A film type magnetic recording medium including a film substrate, and a magnetic film with a plurality of needle shaped magnetic grains dispersed in the magnetic film oriented to be substantially perpendicular to the surface of the magnetic film and vertically overlap one another. The film is coated on the substrate and then dried in a magnetic field perpendicularly oriented to the film surface so that the grains are fixed in an orientation substantially perpendicular to the film surface.
