Abstract:
A method of manufacturing a magnetic recording medium comprising the steps of:a) forming at least one support layer on at least a first major surface of non-magnetic substrate; b) forming at least one magnetic layer comprising magnetic pigment particles atop said at least one support layer to form a magnetic recording medium having multiple layers; c) exposing said magnetic recording medium to a first magnetic field of up to about 2500 gauss when the average percent solids of said multiple layers is less than about 40% collectively, and d) exposing said magnetic recording medium to at least one additional magnetic field of from about 3500 to about 7000 gauss when the average percent solids of said multiple layers is from about 43% to about 60% collectively, wherein said magnetic pigment particles in said magnetic layer are oriented in a longitudinal direction.
