A magnetic recording medium on glass or Al substrates with film structures of CrV/NiAl/CrMo/CoCrTa/CoCrPtTaNbB and CrMo/CoCrTa/CoCrPtTaNbB exhibit high coercivity and high signal-to-medium noise ratio. The medium can be used for high-density longitudinal magnetic recording. Embodiments include forming a sub-seed layer on a NiP-plated aluminum substrate, and sequentially depositing a seed layer, an underlayer, an intermediate layer and a magnetic layer on the substrate. The magnetic layer contains at least six elements, including Co, Cr and B.
