Abstract
A write head has a pole tip, a write yoke connected to the pole tip, a write return yoke, a write shield, and one or more side shields disposed in close proximity to the pole tip. The write return yoke connects to the write yoke on one end and the write shield on a different end. The one or more side shields are separated from the pole tip and write shields by a non-magnetic material and therefore are 'floating' and not directly coupled to the write shield or pole tip.
