Abstract: A content recording apparatus adapted to the surveillance camera system. A HDD (Hard Disk Drive) cyclically records an MPEG-PS (Program Stream) and an INDEX data into an MPEG file and an INDEX file in a hard disk. When a power is provided, a CPU determines whether last recording operation by the HDD is abnormally ended referring to a managing file or not. If a determination result is affirmative, the CPU reads out the MPEG-PS from each a frame of the MPEG file, and reads out the INDEX data from each 24 bytes of the INDEX file. If an error of the hard disk causes a failure of a reading operation, the CPU executes a clear process. As a result, the error of the hard disk is restored. If the reading operation succeeds, the CPU detects a point of discontinuous time of the MPEG-PS or the INDEX file. When the error is restored or the point of discontinuous time is detected, a normal recording operation is started.
