Magnetic recording media comprise non-metallic substrates which are coated with a seedlayer of carbon or silicon. The seedlayer improves the magnetic recording characteristics of a subsequent magnetic layer. The effect of the seedlayer is further enhanced by use of an underlayer, preferably a chromium or chrome alloy ground layer, between the seedlayer and magnetic layer.

Carbon seedlayer on non-metallic substrates for magnetic recording media

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.
