Abstract
A magnetic recording medium comprising a non-metallic substrate having a seedlayer thereon of carbon or silicon. The seedlayer improves the magnetic recording characteristics of a subsequent magnetic layer by smoothing out irregularities on the non-metallic substrate surface such that a surface of the seedlayer adjacent the magnetic layer is smoother than the surface of the substrate.
