摘要

The use of a fluorocompound comprising a perfluoropolyoxyalkyl/alkylene chain with an average molecular weight of not less than 800 and an atomic group of a cyclic/noncyclic polyether as a low-scattering lubricant/surface modifier (such as a water repellant) serves to improve the sliding durability of magnetic recording media.
