Abstract
A method of fabrication and a magnetic transducer having an inverted write element with a zero delta in pole tip width to provide improved bi-directional control over write track width and written erase bands on media. The transducer includes a top pole and a bottom pole configured to provide the same write track width and relatively small erase bands when either pole is the trailing pole depending on direction of movement of the media relative to the transducer. The bottom pole has an upper portion and a lower portion. The bottom pole upper portion width is less than the bottom pole lower portion width. The top pole has a main portion formed opposite to the bottom pole upper portion. The top pole main portion has a main portion width which is equal to the bottom pole upper portion width.
