Plural carbon-containing overcoats are formed on a media-facing surface of an information storage system head. The plural carbon-containing overcoats can mitigate corrosion without increasing head-media spacing. A first of the overcoats may be formed prior to creation of contact or air bearing features on the media-facing surface, with a second overcoat formed after creation of air bearing features. The first overcoat may be etched back substantially or completely prior to formation of the second overcoat. Laminated carbon-containing overcoats may have greater strength and/or coverage than non-laminated overcoats of the same thickness. The overcoats may be formed of several forms of diamond-like carbon (DLC) or silicon-carbide (SiC).
