Abstract
A method, system and apparatus are disclosed for forming a lubricant film for magnetic recording applications. The method includes, in certain embodiments, providing at least one substantially solvent free lubricant having a plurality of lubricant molecules with each lubricant molecule comprising a polymer chain having a backbone section and at least one functional end group. The method also includes treating the at least one substantially solvent free lubricant with a physical treatment to cross-link the backbone section of each polymer chain with at least one other molecule to create a cross-linked lubricant.
