Abstract

An NiAl layer was introduced as a seed layer and as a domain wall pinning layer for Co-Pd multilayer perpendicular magnetic recording media. Grain size of the Co-Pd multilayer media was reduced significantly with the introduction of an NiAl seed layer. The angular dependence of the coercivity data indicated a domain wall pinning effect of the NiAl layer which was introduced into the Co-Pd multilayer media. Improvements were observed in read/write tests on a Co-Pd multilayer medium with an NiAl pinning layer.
