Beschreibung
Zusammenfassung:	The disclosed invention provides a high-reliability magnetic recording apparatus, magnetic recording medium, and a method of manufacturing such a medium in a high-density magnetic recording apparatus which comprises a magnetic disk revolving at a high speed and a magnetic head which flies as low as possible over the magnetic disk. A lubricant layer formed on the outermost surface of a magnetic recording medium is constituted by a lubricant which comprises fluoropolyether as the principal ingredient. The fluoropolyether lubricant is characterized in that alcohol hydration distribution which corresponds to difference between the greatest and smallest alcohol valences among the component molecules of the fluoropolyether is adjusted to 0.48 or less and an average alcohol valence among the component molecules is adjusted to fall within a range of 3.00 to 3.91.
