Pre-recorded magnetic audio tape for learning

Claim 1

A magnetic audio tape employable as a learning aid, said tape comprising: at least first and second adjacent tracks extending longitudinally in a direction of advancement of the tape; both of said first and second tracks including separate longitudinally spaced pre-recorded sections separated by intermediate sections; said pre-recorded sections of said first and second tracks being staggered with respect to each other in said direction of advancement, such that all of said pre-recorded sections of said first track are entirely out of alignment with all of said pre-recorded sections of said second track, taken transversely of said direction of advancement, and such that all of said pre-recorded sections of each of said tracks are entirely transversely aligned with portions of said intermediate sections of the other of said tracks; said pre-recorded sections having thereon recorded sounds, each said recorded sound of said first track being related as a learning aid to the next succeeding said recorded sound of said second track, taken in said direction of advancement, whereby upon reproduction of one of said tracks there may occur on said intermediate sections thereof low volume magnetically induced recorded sounds from the respective pre-recorded sections of the other of said tracks; and means for rendering audibly indistinguishable said low volume magnetically induced recorded sounds, said means comprising background sounds recorded along the entire length of all of said intermediate sections of both of said tracks, said background sounds having a volume level substantially lower than that of said recorded sounds but high enough to render audibly indistinguishable said low level magnetically induced recorded sounds.
