ABSTRACT:
A magnetic recording medium comprising a glass or glass-ceramic substrate is formed by sequentially depositing thereon a partially oxidized NiP seed layer, an underlayer and a magnetic layer. The partially oxidized NiP seed layer is formed by reactive sputtering in a gas mixture of argon and oxygen. The resulting magnetic recording medium exhibits low medium noise and high coercivity rendering it suitable for high density magnetic recording.
