A magnetic audio tape comprises at least two tracks in one direction of advance of the tape. Each of the tracks has pre-recorded sections at sufficient intervals therebetween, with the recorded sections of one of the tracks being staggered with respect to the recorded sections of the other track in such a manner that all of the recorded sections of the tracks are not opposite to each other in the transverse direction of the tape. Each of the recorded sounds in the recorded sections of one track is closely related as a learning aid to the recorded sound of the staggered adjacent recorded section of the other track.
