Abstract
Our flux-guided magnetoresistive-read/inductive-write composite head, which we named the WING MR head after the shape of its wide flux-guides, is designed for very low flying height recording. The flux-guides are rectangular and wider than the read width to reduce Barkhausen noise from multi-domain activities of flux-guides. The WINGMR head also has very small coils so that it can be fabricated on a very small slider. Test results show good offtrack characteristics and high linear density resolution at a flying height of 0.03 μm. The wide flux-guides reduce Barkhausen noise without lowering offtrack performance.
