摘要：
In a magnetic head, a multilayer film is disposed, the multilayer film including metal magnetic films and non-magnetic films that are alternately laminated, and a boundary between the multilayer film and a magnetic oxide substrate or a non-magnetic substrate on which the multilayer film is to be formed is parallel with a gap section at a surface of the magnetic head for sliding with respect to a magnetic recording medium. The metal magnetic films constituting the multilayer film have two or more types of thickness, or the metal magnetic films constituting the multilayer film have a uniform thickness, and the uniform thickness t satisfies t
