摘要： An arbitrary pattern write head assembly for writing timing-based servo patterns on magnetic storage media is provided, comprising: (a) a first pole piece comprising a substrate comprising a magnetic material, said substrate having a major surface; (b) a plurality of electrically conducting windings formed on the major surface; and (c) a second pole piece formed on the substrate, with a portion thereof formed above the plurality of electrically conducting windings and electrically insulated therefrom, the second pole piece having at least one opening therethrough defining a gap above the electrically conducting windings and the substrate, the second pole piece comprising at least two layers, each layer comprising a magnetic material. A method of batch fabricating servo writer heads is also provided for batch fabrication of servo writer heads at a very low cost. The method enables fabrication of heads capable of azimuthal recording commonly practiced in the video recording art. Hard nitrided Fe/NiFe poletip materials are used to minimize wear in tape head use.
