To solve such a problem that an accurate recording of track numbers has been difficult when continuously recording plural musics of an analog record on a CD-R.

The time required for recording of plural musics on an analog record is beforehand stored on a table 61 of a RAM 42. Then, a timer 43 is provided to measure recording history time of the musics on the CD-R. When the recording required time of the table 61 matches with the time measured by the timer 43, a track number is incremented and the number is recorded in a subcode region of the CD-R.
