Abstract:
A magnetic recording medium having a polyester substrate with at least one magnetic recording layer coated thereon, wherein the substrate is a polyester film which has been modified by atmospheric plasma treatment prior to coating. The treated substrate film exhibits a contact angle of at least about 20 degrees less than the contact angle of an unmodified polyester film and has an average peel adhesion to a magnetic recording coating of at least about 0.2 N/mm.
