    • A device for manufacturing magnetic recording media in which the magnetic particles in the recording layer are oriented in a preferred direction, the fluid coating applied to the base being subjected to the action of a magnetic field produced in the air gaps between the spaced apart poles of two magnetic circuits, one on each side of the coated face, arranged symmetrically with respect to the plane of the coated base, the edges of the poles adjacent to the coated base terminating in screening elements shaped in such a way that the distance between the surfaces of the screening elements facing the coated base and the coated base itself increases as the screening elements extend away from the edges of the poles. A high degree of magnetic anisotropy in the recording layer can also be obtained when the magnetic circuits are at a relatively large distance from the still fluid magnetic coating.
    • 一种用于制造磁记录介质的装置,其中记录层中的磁性颗粒沿优选方向取向,施加到基底的流体涂层受到在间隔开的极间的空隙中产生的磁场的作用 相对于被涂覆的基体的平面对称地布置有两个磁路,一个在涂覆面的每一侧上,与被涂覆的基底相邻的极点的边缘终止于以这样的方式成形的屏蔽元件: 面向涂覆的基底的筛选元件和涂覆的基底本身随着筛分元件远离极的边缘而增加。 当磁路距离静止流体磁性涂层相对较大的距离时,也可以获得记录层中的高度的磁各向异性。
