ABSTRACT:
The perpendicular magnetic orientation of a magnetic layer containing platelet-form ferromagnetic particles coated on a web support is effectively performed by passing a web having thereon the coated magnetic layer in an undried state through a magnetic field formed by plural pairs of opposite pole type magnets disposed in the travelling direction of the web with a gap between adjacent pairs of magnets, while supplying drying air through each gap onto the surface of the travelling web to substantially complete the drying of the coated layer while the web is in the magnetic field. A partition may be inserted in each gap so that the lower end of the partition is close to the upper surface of the travelling web to divide the gap into a front section and a back section, and the drying air may be passed through these sections.
