Marcos Lederman, Matthew R Gibbons: Dual stripe spin valve sensor without antiferromagnetic pinning layer. Western Digital, Carr & Ferrell, October 5, 2004: US06801411 (148 worldwide citation)

A dual-stripe current-pinned spin valve magnetoresistive read sensor includes a first soft ferromagnetic (FM) layer separated from a second soft FM layer by a first spacer layer formed of conductive material. The first spacer layer is also configured to receive a first biasing current for generating ...

PROBLEM TO BE SOLVED: To dispense with the necessity of an antiferromagnetic(AFM) layer in a sensor, to make realizable doubling of read signals and an operation in a differential mode showing high symmetry, and to make achievable a high reading performance. SOLUTION: The read sensor is provided wit ...
