Abstract:
A device for exchanging data with a magnetic medium, comprising:a substrate; a first pole formed of ferromagnetic material, disposed above said substrate, and having an edge that forms an air bearing surface; a second pole formed of ferromagnetic material, disposed above said first pole, and having an edge that forms said air bearing surface; a coil layer that is recessed into said first pole; a write gap layer formed of non-magnetic, electrically insulating material and disposed between said first pole and said second pole, said write gap layer having an edge that forms said air bearing surface; a coil separation layer formed of non-magnetic, electrically insulating material and disposed between said coil layer and said second pole; and a second pole pedestal formed of ferromagnetic material and magnetically connected to said second pole at a second pole tip portion of said second pole, wherein said write gap layer is disposed between said first pole and said second pole pedestal, and said second pole pedestal includes an edge that forms said air bearing surface.
