Abstract:
A magnetic write element comprising:a first pole formed of magnetic material and having a first pole tip portion;a second pole disposed above said first pole and having a second pole tip portion including a bottom surface, wherein said second pole tip portion is aligned with said first pole tip portion, said second pole being formed of magnetic material that is connected to said first pole distal said pole tip portions;a second pole pedestal connected to said second pole tip portion and disposed between said second pole tip portion and said first pole tip portion, wherein said second pole pedestal has a first surface, a second surface, a substantially planar first sidewall, and a substantially planar second sidewall, and formed of magnetic material, said second pole pedestal having a tapered shape wherein said first surface of said second pole pedestal is wider than said second surface of said second pole pedestal;a write gap formed of non-magnetic and electrically insulating material disposed between said second pole pedestal and said first pole tip portion;a first pole pedestal disposed between said first pole tip portion and said write gap and connected to said first pole tip portion and bounded by said first and second sidewalls;an insulating layer formed of non-magnetic and electrically insulating material disposed between said first pole and said second pole; anda conductive coil imbedded within said insulating layer.
