Abstract
A manufacturing method for a magnetic recording medium is disclosed which comprises the steps of forming a metallic magnetic layer on a non-magnetic substrate such as a polyester film with or without a non-magnetic metal layer deposited thereon by a method of electroless plating or electroplating, forming a vapor-phase plasma-polymerized layer of a silane compound, e.g. 1,1,2,2-tetramethyl disilane and 1,1,2,2,3,3-hexamethyl trisilane, and forming a thin layer of a fluorocarbon resin. The thus manufactured magnetic recording medium has advantages in several properties such as the surface lubricity sufficient to give satisfactory smoothness of travelling, durability in abrasion resistance and weatherability.
