Bicrystal cluster magnetic recording medium

摘要

A magnetic recording medium having low medium noise and suitable for high density magnetic recording is produced with a bicrystal cluster magnetic layer (33) on a glass or glass-ceramic substrate (30). An underlayer (32) which is formed with a (200) crystallographic orientation induces the formation of a bicrystal cluster microstructure in a magnetic alloy layer (33) epitaxially grown on the underlayer.
