Abstract: Coated magnetic recording media, especially video tapes and computer tapes, comprising a non-magnetic base carrying a magnetic coating which consists of a dispersion, essentially containing a finely divided magnetic pigment in an organic binder and at least one lubricant. A compound of the formula in which n is an integer of from 1 to 3 and R is alkyl, alkoxyalkyl or aralkyl, each of 3 to 18 carbon atoms, is used as a lubricant. The products have high abrasion resistance coupled with only little transfer of material to the magnetic heads even under fluctuating climatic conditions.
