Abstract
A magnetic recording medium having low medium noise and suitable for high density magnetic recording is produced with a bicrystal cluster magnetic layer on a glass or glass-ceramic substrate. An underlayer which is formed with a (200) crystallographic orientation induces the formation of a bicrystal cluster microstructure in a magnetic alloy layer epitaxially grown on the underlayer.
