Abstract
A method is provided for coating one or more fluid layers on a substrate to form magnetic recording media such as magnetic tape and diskettes. The method takes advantage of fluid coating formulations having a particular rheology that enables the coating of one or more magnetic layers with reduced thicknesses while achieving increased coating speeds. With proper rheology, one or more layers can be coated on a substrate traveling at increased speeds while maintaining desired coating thicknesses.
