ABSTRACT:
A method for manufacturing a magnetic recording medium including the steps of applying a magnetic coating containing magnetic particles therein to a support, subjecting said support having the magnetic coating thereon to magnetic orientation treatment while the magnetic coating is still in fluid condition and thereafter drying the magnetic coating, characterized in that said magnetic orientation is effected by passing said support having the magnetic coating thereon through a magnetic orientation field generated from magnetic field generating means which comprises one or more permanent or DC magnets and an array of a plurality of parallel elongated members of a soft magnetic material arranged substantially in a plane close and parallel to said support and adapted to be magnetized by said magnet or magnets.
