ABSTRACT:
A recording head for use with a storage medium is provided. The recording head includes a substrate, a magnetic pole, a first magnetic bias structure positioned on a first side of the magnetic pole, and a second magnetic bias structure positioned on a second side of the magnetic pole, Spacer material is positioned between the magnetic pole and the first magnetic bias structure and between the magnetic pole and the second magnetic bias structure.
