    Abstract: Embodiments relate to lubricants disposed over magnetic storage media, such as rotatable thin film magnetic discs. One embodiment comprises a lubricant compound of a fluoropolyether chain having one or more carbonyl-imide pairs. In one aspect, the carbonyl-imide pair may be located at one end, both ends, and/or in the middle of the fluoropolyether chain. Another embodiment comprises a method of manufacturing a magnetic storage medium comprising forming a magnetic layer over a substrate. Then, a lubricant topcoat is applied over the magnetic layer. The lubricant topcoat may comprise a fluoropolyether having one or more carbonyl-imide pairs. Still another embodiment comprises a magnetic storage medium including a substrate, a magnetic layer formed over the substrate, and a lubricant topcoat formed over the magnetic layer. The lubricant topcoat may comprise a fluoropolyether having one or more carbonyl-imide pairs.
