Abstract: Magnetic recording medium comprises a substrate (11), a support (13) on the substrate, a granular ferromagnetic base layer (15) made of a Co alloy on the support and having a thickness of 1-30 nm, and a ferromagnetic coating (17) formed on and in contact with the base layer and comprising an element selected from Co, Fe and Ni. The coating has an effective thickness of 1-40 angstroms. An Independent claim is also included for a process for the production of the recording medium.
