Abstract: A method of manufacturing a magnetic head is provided which can improve controlling a thickness of a gap layer. A coil base layer having at least a surface layer formed of one or two or more alloys selected from Au, Ru, and Rh is formed on a contact layer. Thereby, since a surface of the coil base layer is not oxidized due to air exposure, the contact layer is not oxidized. As such, the coil base layer protects the contact layer, so that it is not necessary to perform an etching process for removing an oxide layer, as in the related art. Therefore, it is possible to further improve controlling a thickness of a gap layer without cutting the gap layer by the etching process, as compared with the related art.

Abstract translation: 提供一种制造磁头的方法，其可以改善控制间隙层的厚度。 在接触层上形成至少具有由一种或两种以上选自Au，Ru和Rh的合金形成的表面层的线圈基层。 因此，由于线圈基层的表面由于空气暴露而不被氧化，所以接触层不被氧化。 因此，如现有技术那样，线圈基层保护接触层，从而不需要执行去除氧化物层的蚀刻工艺。 因此，与现有技术相比，可以通过蚀刻工艺进一步改进控制间隙层的厚度而不切割间隙层。
