Abstract
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.
