ABSTRACT:
This disclosure pertains to a cartridge containing an endless magnetic tape having recorded information in combination with a second spool of endless tape having written information thereon. The two spools are linked together so that both tapes are synchronously driven by a conventional tape player adapted to operate the magnetic spool alone. The user views the information on the indicating tape while listening to the playback of the recorded signal by utilizing a magnifying lense adapted to selectively enlarge each longitudinal track of written information, such as lyrics, corresponding to the longitudinal tracks of related signal, such as music.
