Abstract

A method for improving corrosion resistance while maximizing magnetic performance of a magnetic disk employed in data storage applications. The invention includes providing a substrate and forming a first layer above the substrate, the first layer having a first degree of abrasion resistance. The invention includes forming a second layer such as a Ni-containing layer above the first layer, the Ni-containing layer having a second degree of abrasion resistance lower than the first degree of abrasion resistance. The invention further includes forming grooves in the Ni-containing layer.
