Disclosed is a method to convert a low resistance cell in a MRAM device to a capacitive cell. The low resistance cell has a plurality of layers on a substrate. At least one layer remote from the substrate is sensitive to oxygen infusion. The method includes removing a cap layer of the cell and applying an oxygen barrier around the cell to expose at least a part of a surface of the at least one layer remote from the substrate. The at least one layer is oxidized. The oxygen barrier is removed.

A disk drive spoiler for reducing particle accumulation in a hard disk drive is provided. The spoiler includes a body portion for directing airflow generated by a rotating disk, the rotating disk comprising a middle diameter and an outer diameter wherein the body portion directs airflow away from the outer diameter of the disk. The spoiler also includes an end portion for directing airflow away from the middle diameter of the disk towards the outer diameter of the disk wherein the body portion comprises a perforation through the body for reducing suction of particles onto the disk surface.

The present invention relates to HDD screws, and more specifically to lubricating the HDD screws. HDD screws may be coated in a layer of a PFPE based lubricant to reduce friction while fastening the screw into a HDD. In addition to providing superior lubricity and reduced friction during fastening and longer shelf life, PFPE lubricated screws provide narrower clamping load distribution and lower particle generation compared to currently used screw lubricants. Furthermore, because PFPE lubricants are also used to lubricate magnetic disk surfaces, the HDD screws may provide a reservoir for replenishing depleting lubricants on the magnetic disk drive surface.
