Abstract: The magnetic recording material has a non magnetic carrier which is coated with a polymer binding material that contains a dispersion of fine pigments of needle type magnetic particles. Two types of pigment are used with the first having a concentration of 15-45 meters per gram and the second having 5 meters per gram higher. The mix is with a first pigment of 50-59 % and the second pigment with 41-50%.
