ABSTRACT:
A damping material (19) is provided on one of the two side faces (7, 8), of a magnetic head having two plate shaped ferrite core limbs (3, 4). The material consists of a synthetic resin filled with less than 30% by volume of filler having a density of more than 10.times.10.sup.3 kg/m.sup.3. The filler is at least 74% by weight of the damping material and the density of the damping material is larger than 4.times.10.sup.3 kg/m.sup.3 and its modulus of elasticity ranges between 10.sup.7 and 10.sup.9 Pa.
