ABSTRACT:
Provided is a lubricant solution for a magnetic recording media, wherein the lubricant solution includes a lubricant that is excellent in chemical stability and capable of imparting excellent lubricity to the lubricant solution, and a solvent having a suitable dissolving power for the lubricant, being excellent in drying properties and not influential over the ozone layer. Also provided is a lubricant solution including a lubricant and a fluorinated alkyl ether. Further provided is a lubricant solution including a compound of the formula (HO—CH2—CF2(OCF2CF2)dO—)3Y, wherein Y is a trivalent perfluorohydrocarbon group, as the lubricant and 1,1,2,2-tetrafluoroethyl-2,2,2-trifluoroethyl ether as the fluorinated alkyl ether.
