When an audio signal and music piece name information are recorded onto a CD-R, timing for inputting the music piece name information is not restricted to timing just before "finalize". An ID is allocated to the CD-R inserted into a recorder and written into a PMA and a memory. The audio signal is recorded into a PGA on the CD-R. The music piece name information and the like are inputted by text data and stored into the memory in correspondence to the ID. Upon "finalize", the text data is read out from the memory and written as TOC information into a lead-in on the CD-R. In case of ejecting the CD-R without finalizing, a track number, start time, and end time are recorded into the PMA. The ID and the text data are held in the memory. When this CD-R is subsequently inserted, they can be read out from the memory on the basis of the ID. Before "finalize", the text data which is recorded as TOC information can be inputted anytime.
