A write head having a write pole with a tip portion defining a pole tip and a paddle portion extending from the tip portion away from the pole tip, the paddle portion defining a back edge. The write head also has a coil structure having at least two active turns crossing the paddle portion, wherein a back of the coil structure is no more than 1 micrometer past the back edge of the write pole. In some implementations, a length from the pole tip to the back edge is no more than 4.5 micrometers.
