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 or contact recording. It has 0.05 μm-thick NiFe single layer flux-guides. The flux-guides are rectangular and wider than the read width. Test results show high linear density resolution and good offtrack characteristics at a flying height of 0.03 μm. The wide flux-guides reduce Barkhausen noise without lowering offtrack performance
