US Patent 7573683 Write heads with floating side shields and manufacturing methods

A write head for a media drive suited for perpendicularly recording data in adjacent magnetic recording media, the media having a magnetic recording layer and a soft underlayer (SUL). The write head has a pole tip, a write yoke connected to the pole tip, a write return yoke, a write shield, one or more conductive coils surrounding the write yoke, 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.
