ABSTRACT:
A glass or glass-ceramic substrate comprising about 0.5 to about 32 wt. % Li.sub.2 O is employed as a non-magnetic substrate of a magnetic recording medium. Migration of Li from the substrate to the medium's surface is prevented by forming an amorphous NiP sealing layer on the substrate, with an optional adhesion enhancement layer therebetween. Embodiments include surface oxidizing the amorphous NiP sealing layer for enhanced recording performance.
