High density, multi-layer, magneto-optical (HDMMO) information storage and retrieval media having improved tribological properties when used in high-density storage devices employing very small head flying heights are formed by providing an ultra-thin, protective flash layer overcoat (FLO)/lubricant topcoat layer system over the surface of a HDMO medium comprising a metal superlattice. Embodiments of the present invention include forming the FLO layer of an amorphous, abrasion-resistant, carbon-based, diamond-like material not greater than about 10 Å thick and selected from CNx, CHx, and CNxHy, and providing the lubricant topcoat on the FLO layer as an about 15-25 Å thick layer of a fluoropolyether or perfluoropolyether material, e.g., perfluoropolyethylene (PFPE).
