Abstract
A method for fabricating a single top spin valve head that is capable of reading ultra-high density recordings. Said top spin valve has a CoFe free layer for high GMR ratio, which is grown on a NiCr/Ru layer to provide better magnetic properties and has a ferromagnetically coupled CoFe/NiCr/CoFe laminated pinned layer for thermal stability and robustness.
