A magnet containing a lubricant with excellent chemical stability that can provide excellent lubricity, and a solvent that has an appropriate dissolving power for the lubricant, has excellent drying characteristics, and does not affect the ozone layer. Providing a lubricant solution for recording media. A lubricant solution containing a lubricant and a fluorine-containing alkyl ether. For example, a compound represented by (HO—CH 2 —CF 2 (OCF 2 CF 2 ) d O—) 3 Y (wherein Y is a trivalent perfluorohydrocarbon group) as a lubricant, 1,1,2,2-Tetrafluoroethyl-2,2,2-trifluoroethyl ether is used as the ether. |
