ABSTRACT:
A method for producing a magnetic recording medium while minimizing electrostatic charge buildup on the medium during production. The method comprises applying a liquid material over a surface of a moving web to form a continuous wet coating thereon and smoothing the wet coating with a flexible blade having two major surfaces. The flexible smoothing blade comprises a conductive layer and is positioned so that a portion of one major surface is in contact with the wet coating so that electrostatic charge on the coated web is continuously dissipated.
