Abstract

PURPOSE:To improve the interlayer adhesion of a protective coating film and to improve the durability by providing the protective coating film on a magnetic layer by a specific method. CONSTITUTION:On the surface of magnetic layer 2 provided on base 1, protective coating layer 3b whose cross section is in a tooth shape is provided in the gravure coating method and then leveled by using device 6, such as a film blade, to obtain flat-surface protective coating film 3c.
