摘要： Aspects are directed to recording media with enhanced magnetic properties for improved writability. Examples can be included or related to methods, systems and components that allow for improved writability while reducing defects so as to obtain uniform magnetic properties such as uniformly high anisotropy and narrow switching field distribution. Some examples include a recording medium with an exchange tuning layer inserted between the hard layer and the soft, semi-soft or thin semi-hard layer so as to maximize the writability improvement of the media. Preferably, the exchange tuning layer is granular and reduces or optimizes the vertical coupling between the hard layer and the soft, semi-soft or semi-hard layer of a magnetic recording or storing device.

摘要： A flash chromium capping layer is deposited on a magnetic layer for improved corrosion resistance, reduced poisoning due to the absence of a protective overcoat or presence of discontinuities in a protective overcoat, and for reduced media noise do to inter-granular exchange coupling. Embodiments include depositing a flash chromium layer having a thickness up to about 10 Å on an upper magnetic layer and depositing an overlying lubricant topcoat. An optional protective overcoat, such as a carbon-containing protective overcoat, can also be deposited on the chromium capping layer. The chromium capping layer forms a protective oxide coating where exposed, as due to the absence of or at discontinuities in the protective overcoat.
