Application of enhanced layer of crystal nuclei by making use of tantalum alloy-based sputter target

摘要

In a method for producing a magnetic recording medium, a seed crystal layer is applied by first spraying from an alloy element tantalum-based electrode, which softens the structure of the subsequently applied substrate layer and results in anisotropy of the applied magnetic layer. The alloying element is selected based on the specific susceptibility and / or atomic radius and / or solubility in tantalum.
