A method of manufacturing a replicated magnetic reproduction medium, such as a magnetic-tape cassette provided with a music recording, which reproduction medium includes a magnetic tape having a plurality of tracks extending parallel to one another in the longitudinal direction at specified spacings within certain limits from one another. The reproduction medium thus manufactured serves for the reproduction of the replicated signals by a magnetic reproducing head having a plurality of transducing gaps situated at specified spacings within certain limits from one another. During reproduction, a specified normal tape tension within certain limits is sustained, resulting in a normal surface pressure between the tape and the head face of the reproducing head. During replication the tape is moved over a head face of a magnetic replication head also having a plurality of transducing gaps with a certain spacing from one another. The the tension in the tape is increased relative to the normal tension. Another characteristic feature is that, in order to compensate, at least partly for deviations in the positions of the tracks which would arise as a result of the increased transverse contraction of the tape caused by the increased tension, the spacings between the centers of the transducing gaps of the replication head are smaller than those of the reproducing head.
