摘要：A film type multilayer magnetic recording medium comprised of a film applied
to a substratum in which coating film needle-shaped magnetic grains are orientated with
their longitudinal axes perpendicular to the film surface in a multilayer state and having a
film thickness of 1.1 to 2.0 times the average length of the grains, has an excellent
property, because the angular ratio (Br Bs) of both horizontal and vertical components
respectively are 0.6 or more. As a result, it is possible to attain a high density recording.
The film type multilayer magnetic recording medium of the present inventions is
manufactured by applying a fluid film forming material, in which neddle-shaped magnetic
grains are dispersed to form a coating film having the thickness of 1.1 to 2.0 times the
average length of the magnetic grains on a substratum, and then drying or hardening the
film forming material in a magnetic field orientated perpendicularly toward the film
surface.
