ABSTRACT:
The present invention provides a longitudinal magnetic recording media having a substrate, a Co or Co alloy based layer and an underlayer disposed between the substrate and the magnetic layer comprised of a material having a B2 ordered crystalline structure, preferably NiAl or FeAl. A thin Cr intermediate layer of about 1.0 nm to 5.0 nm thick may be positioned between the underlayer and the magnetic layer.
