A digital camera comprises an imaging device; an internal memory; an attachment device that attaches a storage medium; a medium detector that detects whether the storage medium attached to the attachment device is a storage medium limiting overwrite; and a record control device that controls so as to store image data taken by the imaging device in the storage medium attached to the attachment device. When the medium detector detects that the storage medium attached to the attachment device is the storage medium limiting overwrite, the record control device controls so as to store data management information of the image data recorded in the storage medium limiting overwrite in the internal memory.
