Magnetic recording media, the magnetic coating of which consists of a dispersion of elongated ferromagnetic chromium dioxide particles in an organic binder, the dispersions exhibiting particularly good storage stability. This is achieved by admixing 0.5 to 6% by weight, based on the amount of chromium dioxide pigment, of the zinc salt of an aliphatic carboxylic acid of 8 to 18 carbon atoms, during the manufacture of the chromium dioxide dispersions. Chromium dioxide dispersions with good storage stability and a high degree of orientation of the elongated magnetic particles in the magnetic coating are thus obtained in a simple manner.
