Lubricant for thin film storage media

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. For example, the carbonyl-imide pair may be located at one end, both ends, and/or in the middle of the fluoropolyether chain.
