Abstract
Systems and methods for tuning seed layer hardness in components of magnetic recording systems are described. One such system includes a substrate including a component of a magnetic recording system, a first deposition source configured to deposit a seed layer material on a portion of a top surface of the substrate at a first angle, and a second deposition source configured to deposit a carbon material including sp3 carbon bonds on the portion of the top surface at a second angle not equal to the first angle, where the first deposition source and the second deposition source deposit the seed layer material and the carbon material, respectively, simultaneously. The component can be a slider or a magnetic medium.
