Magnetic recording media and apparatus

本发明的目的是提供以高速旋转的磁盘和以低浮起高度浮在磁盘上的磁头构成的高密度磁记录装置，该磁记录装置具有较高的可靠性。还提供了用于该装置的磁记录媒体及其制造方法。上述目的通过用氟聚醚润滑剂在磁记录媒体的最表面形成润滑膜而达到。该润滑剂的主成分是具有醇官能团的氟聚醚，该氟聚醚的以分子内醇价数的最大值和最小值之差表示的醇价数分布在0.48以下，分子内醇价数为3.00～3.91。 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.
