Abstract:
A magnetic recording medium I having a tape form, comprising a nonmagnetic substrate III, at least one layer applied to this substrate, whereby at least one of these layers is a layer IV for magnetic information storage containing a binder and ferromagnetic pigments, and comprising in at least one of these layers a needle-shaped chromium-containing pigment II of the formula VICr.sup.a Ox.nH.sub.2 O VIwherea is the average valency of the chromium with 3.0<a.ltoreq.3.25,x is the oxygen equivalents determined by the valency of the chromium andn is the water content with 0<n<(4-a)/2,as a ferromagnetic supporting pigment having a ratio of the average length to the average diameter of the pigment II of at least 7 and an orientation ratio of at least 4, wherein the mean modulus of elasticity of the stated layers is not less than 15 GPa in the longitudinal direction of the recording medium I.
