Abstract
The endless recording which enables partial saving of recording contents and facilitates editing or management is to be achieved. To this end, if recording has been made for a pre-set time, such as one hour, a new region is secured to continue the recording, at the same time as a region carrying the oldest recorded contents is sequentially evacuated in an amount equal to the newly secured region. The partial saving region (00:10:00:00 to 00:20:00:00) is not to be evacuated.
