    • 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.
    • 一种制造磁记录介质的方法,包括以下步骤:将含有磁性颗粒的磁性涂层施加到载体上,在磁性涂层仍处于流体状态下使其上具有磁性涂层的所述载体进行磁性取向处理,然后干燥磁性 涂层,其特征在于,所述磁性取向通过使其上具有磁性涂层的所述支撑件通过磁场产生装置产生的磁取向场来实现,所述磁场产生装置包括一个或多个永久或DC磁体和多个平行细长构件的阵列 一种软磁材料,其基本上布置在与所述支撑件相近并平行的平面中并且适于被所述磁体或磁体磁化。
