    • A magnetic recording medium having the outermost layer holding liquid crystal molecules of specified monocyclic, dicyclic and tricyclic structures as a lubricant; and a magnetic recorder/reproducer having a magnetic recording medium for recording information and a magnetic head for recording/reproducing information on/from the magnetic recording medium, wherein the minimum interval between the geometrical average planes of the magnetic recording medium and the magnetic head is 50 nm or less and liquid crystal molecules of specified structure are held as a lubricant in the outermost layer of the magnetic recording medium. The lubricant contains liquid crystal molecules having phase transition from the solid phase to the liquid phase and intermediate properties between liquid and solid. The lubricant can release the kinetic energy produced by sliding through phase transition. The magnetic recording medium and the magnetic recorder/reproducer can satisfy all the characteristics of durability against continuous sliding, low adhesiveness and high meniscoid force.
    • 一种磁记录介质,其具有保持指定的单环,二环和三环结构的液晶分子的最外层作为润滑剂; 以及具有用于记录信息的磁记录介质和用于在磁记录介质上记录/再现信息的磁头的磁记录器/再现器,其中磁记录介质和磁头的几何平均平面之间的最小间隔是 50nm以下,在磁记录介质的最外层中,作为润滑剂保持规定结构的液晶分子。 润滑剂含有具有从固相到液相的相变的液晶分子以及液体和固体之间的中间特性。 润滑剂可以释放通过相变滑动产生的动能。 磁记录介质和磁记录器/再现器可以满足连续滑动的耐久性,低粘合性和高显现力的所有特性。
