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.

As a protective film of an element and a slider in a magnetic head, a film is provided which is excellent in adhesiveness to a film forming surface and which shows sufficient corrosion-resistance property with a thinner thickness. To provided this film, according to the present invention, a DLC film as a protective film is formed onto an element portion end surface and a surface of a slider of a magnetic head core. A film deposition step is conducted plural times to obtain the DLC film with a predetermined thickness when the DLC film is formed using an electric discharge.

To provide a high-quality protection target by forming a protective film that is thin and excellent in corrosion resistance. Provided is a protective film forming method for forming a protective film at least on a surface of a protection target. The method comprises: a base film forming step for forming a base film on the surface of the protection target; and a DLC film forming step for forming a diamond-like carbon film on the base film. The base film forming step forms the base film on the surface of the protection target for a plurality of times by repeating a process of depositing the base film in a prescribed thickness and eliminating a part of or a whole part of the base film. Further, the method comprises, before the DLC film forming step, an insulating layer forming step for forming an insulating layer on the surface of the base film on which the diamond-like carbon film is to be formed.

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.
