To provide a voice recorder capable of recording voice without causing a sense of incompatibility, while effectively utilizing a recording medium even when voice is recorded on a different recording medium.

A system control section 6 first performs recording for a first recording medium driving apparatus 8 when a remaining capacity of a recording medium 30 of the first recording medium driving apparatus 8 is equal to a predetermined value or more, even if a recording stop signal is received. On the other hand, the system control section 6 records voice data from a digital signal processing section in a recording buffer 10 channel for every channel when the remaining capacity of the recording medium 30 is less than the predetermined value. When the recording is instructed to be stopped, the file size is compared with the remaining capacity of the recording medium 30 so that only a recordable file is recorded onto the recording medium 30. A second recording medium driving apparatus 9 is then set for recording, and the other files are recorded onto another recording medium 30 in the second recording medium driving apparatus 9.
