Abstract
A magnetic recording medium exhibiting low medium noise is formed by depositing a seed layer on a glass or a glass-ceramic substrate and oxidizing the deposited seed layer, under controlled conditions to induce controlled surface microroughness. The subsequently sputter deposited underlayer exhibits a fine average grain size, such as less than about 20 nm. The magnetic alloy sputter deposited and epitaxially grown on the underlayer exhibits a fine average grain size, such as less than about 15 nm, and magnetic clusters reduced in size.
