  • Patent number: 8609184
    Abstract: A system and method for corrosion problems in magnetic media resulting from moisture penetrating through the carbon layer into the magnetic layer by diffusion or other methods are overcome by processing the carbon overcoat to stop and/or inhibit the moisture penetration. The process involves removing moisture channels from protective overcoats of thin film magnetic media by irradiating the protective overcoat with ultraviolet (UV) radiation in an inert hydrophobic chemical environment. Afterwards, the thin film magnetic media can be removed into ambient atmosphere where it is coated with a lubricant.
