摘要： The present invention manifests a highly excellent effect of allowing the plasma polymerization film to be formed stably for a long time while very rarely suffering occurrence of abnormal discharge during the formation of the plasma polymerization film and promoting the improvement of the yield of products because it adopts as the electrode for implementing plasma polymerization that of the electrodes which is located on the side confronting a surface on which the plasma polymerization film is formed, coats this electrode with a polymer material at a covering ratio in the range of 50-100%, and effects the formation of the plasma polymerization film on an elongate substrate under the operating pressure in the range of 10.sup.-3 -1 Torr. Further, the properties of the plasma polymerization film also become highly excellent.

摘要： A method of manufacturing a magnetic head manufactures a magnetic head having a base, and a laminate stacked on the base and including a magneto-resistive device. The method mechanically polishes a surface of a structure including the base and the laminate close to a magnetic recording medium, wherein the surface of the structure includes an end face of the laminate including an end face of the magneto-resistive device and a surface of the base. Next, the method selectively etches a first region on the surface of the structure close to the magnetic recording medium, wherein the first region includes the surface of the base but does not include the end face of the magneto-resistive device. Subsequently, the method entirely etches the surface of the structure close to the magnetic recording medium.
