Abstract:
The embodiments of the present invention generally relate to a magnetic head having a magnetic lip. The vertical sides and the bottom of the magnetic lip are covered by one or more conductive layers. In one embodiment, the bottom of the magnetic lip is covered by a first conductive layer and the vertical sides of the magnetic lip are covered by a second conductive layer. The conductive layers are made of a material that would not react with oxygen, thus no oxide films are formed on the vertical sides and the bottom of the magnetic lip during the manufacturing of the magnetic head.
