Abstract: PROBLEM TO BE SOLVED: To solve the problem in a conventional record/playback device which performs recording by multiplexing packs, such as that it is substantially impossible to perform after-recording sound or bit map images. SOLUTION: It is recognized whether the contents of audio coded data recorded in an information recording region A are silent or not from the first information in a table T recorded in advance in an information recording region B. When they are judged silent, it is judged that the after-recording of an audio signal is possible, and the audio signal to be after recorded is packed after being coded in the same coding system as the audio coded data recoded in the information recording region A of recording media and. Besides, at the same fixed bit rate from the read-out second and third pieces of information in the table, and it is rewritten on an audio pack prior to recording.  As regards a bit map image, it is rewritten on the pack of the bit map image prior to recording, when the bit map image coded data recorded in the information recording region A are invisible, based on the fourth information in the table A.
