<p>A data transducer, process for fabricating the same and methods for writing data to a magnetic storage media, such as magnetic tape (64), utilizing the lower pole (52) as the trailing edge of a write head (50). The lower pole (52) may be formed of sputtered FeN or FeN-based alloys since it can be formed on the planar substrate instead of overlying the write coil (56) and its associated layers. The lower pole (52) can be processed by wet-etching techniques because its width and edge contours are not critical dimensions which determine recording characteristics. Utilizing the wider and more planar lower pole (52) as the write head trailing edge results in a straighter magnetic transition on the media without the curved edges associated with the fringe fields at the edges of the narrower top pole (62).</p> |
