Abstract
A recording/playback apparatus provided by the present invention comprises at least two recording/playback units. When the size of a recordable area left in a recording medium mounted on one of the recording/playback units undergoing a recording operation first is detected to become equal to or smaller than a predetermined value, a recording operation is started in the other recording/playback unit so that it is possible to obtain a recording result without losing information due to replacement of a recording medium.
