Abstract
A method for producing a magnetic recording medium includes heat-curing a coated substrate to cure a non-magnetic back coat on the substrate and to cure a magnetic front coat on the substrate, and calendering the heat-cured coated substrate to produce the magnetic recording medium. The calendering optionally is off-line calendering during which the substrate passes between opposed, generally non-compliant rolls. Other methods, and magnetic recording media produced by the disclosed methods, also are disclosed.
