ABSTRACT:
A method for manufacturing a magnetic disk includes the step of providing first and second cobalt alloy layers on a substrate. The first cobalt alloy layer is non-ferromagnetic, and the second cobalt alloy layer is ferromagnetic. The non-ferromagnetic layer is deposited on an underlayer. The non-ferromagnetic cobalt alloy provides a better crystal structure for depositing the subsequent ferromagnetic layer and thereby improves its magnetic properties. However, because the first cobalt alloy layer is not ferromagnetic, it does not adversely affect the magnetic characteristics of the disk.
