Information recording/play-backing apparatus

A portable information recording/play-back apparatus comprising:

• an imaging module which images video information;
• a first recording/play-back module which records the video information into a first recording medium, or plays-back the video information from the first recording medium;
• a second recording/play-back module which records the video information into a second recording medium, or plays-back the video information from the second recording medium;
• a battery;
• and
• a controller which controls at least the imaging module, the first and second recording/play-back module,
• wherein the controller judges whether a mode, controlling the first recording/play-back module and the second recording/play-back module, is an imaging mode, controlling so that the first recording/play-back module or the second recording/play-back module records a video information imaged by the imaging module into the first recording medium or the second recording medium, or a dubbing mode which controls a dubbing operation, the first recording/play-back module plays back a video information from the first recording medium and the second recording/play-back module recording the video information which is play-backed from the first recording medium into the second recording medium;
• when the controller judges that the mode is the imaging mode operating on the battery, the controller controls so that if recording into one recording medium is performed, recording into the other recording medium is stopped;
• and
• when the controller judges that the mode is the dubbing mode and the first and second recording/play-back modules operate on the battery, if the battery remaining amount is larger than a threshold value, the controller controls so that the dubbing operation is permitted.
