When audio data are to be stored into a large-capacity memory such as a hard disk device, a shared storage section is set in the memory so as to be used both for storing audio data of one or more songs and for storing song management data for each of the songs that are necessary for reproduction of the audio data. The song management data include data indicative of a stored position, in the shared storage section, of the corresponding audio data. The audio data are sequentially stored into the shared storage section in a predetermined single direction, e.g. from one end toward another of the shared storage section. The song management data are sequentially stored into the shared storage section in an opposite direction to the predetermined single direction, e.g. from the other end toward the one end of the shared storage section.
