Abstract
Abstract An information storage medium such as a CD-ROM has a storage area divided into a plurality of sections, for storing digital audio information and for storing picture information and character information, which are stored independently of each other. The digital audio information includes accompaniment information which represents musical accompaniments relative to songs, and the character information includes information which represents words of the songs to be reproduced in time with the musical accompaniments, in the form of characters, figures, colors, or a combination thereof. An information reproducing apparatus for playing back the information storage medium controls the speed at which the character information is to be output, the shape of characters and figures representing the character information, the colors thereof, or a combination thereof.
