A PVR portion recording image data in an HDD is controlled by a sub-microcomputer. When power supply is started, the sub-microcomputer determines whether a flag is remained to be set or not, i.e., if the flag can not be reset due to an interruption of previous power supply during a recording operation. As a result, if the power failure during the image recording is detected, it notifies a recovery instruction to PVR portion. When PVR portion accepts the notice, it retrieves the image file from HDD that has been interrupted while being recorded, and closes the retrieved file to set it as an effective file. Additionally, it also determines image recording scheduling information, and if the image recording scheduling period is remained, the image recording operation is continued according to the scheduling information.
