Abstract
PURPOSE: To increase the magnetic characters and antiscrabbling characteristics and to improve the adhesion of the ferromagnetic thin film layer to the base, by taking the ground film layer inserted between the substrate and the ferromagnetic metal thin film layer as the two layer construction with specific oxide and metal.
CONSTITUTION: On the substrate consisting of macromolecular molding material such as polyester, the 1st ground film layer consisting of one or more kind of oxides such as titanium oxide, silver oxide, aluminum oxide, silicon oxide and bismuth oxide is formed. Next, the 2nd ground film layer consisting of one or more kind of metals of titanium, silver, aluminum, silocon and bismuth is formed. Further, the 1st layer is formed with the oxide of the same element as the element forming the 2nd layer. Next, the specified ferromagnetic metal thin film layer is formed on the 2nd ground film layer. With this architecture, the 1st ground film layer is bonded with the substrate in excellent manner and the uniform and smooth ferromagnetic thin film layer is formed on the 2nd ground layer.
