Abstract
A system and method for providing corrosion protection for a magnetic read/write head is disclosed. A monolayer surface coating is applied to cover those portions of the under layer of a magnetic read/write head not already covered by a previously applied diamond-like coating. This allows for a thinner diamond like coating than previously applied in the art. The monolayer surface coating can be a self-assembled monolayer, such as an organosilicon for hydroxylated surfaces or carboxylic acids for aluminum or other metal oxides. Alternatively, the monolayer surface coating can be directly applied to the under layer with no diamond-like coating being present. The monolayer surface coating can be applied by a surface immersion process or by a vacuum coating process.
