ABSTRACT:
A magnetic recording medium comprising a magnetic alloy layer having a bicrystal cluster microstructure and, hence, reduced medium noise, is formed by depositing a seed layer on a glass or a glass-ceramic material substrate, oxidizing the seed layer, depositing an underlayer, such as chromium, on the oxidized seed layer, whereby the underlayer exhibits a (200) crystallographic orientation. A magnetic alloy epitaxially grown on the underlayer having a (200) crystallographic orientation exhibits a bicrystal cluster microstructure.
