In order to perform reliable acquisition of album names and song titles while a CD is played back, compressed in MP3 format and filtered, the TOC information of the CD is read out by a CD playback section of a playback/dubbing apparatus. This information is then sent from a system controller to a TOC album relevant information database via a network server and a network communication and corresponding album names and song titles are then acquired. In the case in which corresponding contents information cannot be acquired at the database, the system controller reads out copyright information (ISRC code) of the CD using the CD playback section, searches databases of homepages for music companies or sales companies via the network server and the network communication based on this information, and acquires album names and song titles.
