COATING METHOD AND APPARATUS, METHOD OF MAKING SUBSTRATE ROLL, AND MAGNETIC TAPE

摘要

A method of coating a moving web of a substrate with a coating, includes applying the coating to the substrate to provide a coating thickness distribution curve along a width direction of the substrate such that: the coating thickness decreases from a position where the thickness is the maximum to the opposite ends of the curve and that the distribution curve has the least curvature at the position with the maximum thickness and contains an end portion having a larger curvature than that of the position with the maximum thickness on both sides of the position with the maximum thickness.
