A video recording apparatus includes a recording device having a location information area and a video data area. The location information area stores location information of video data stored in the video data area. The video data area stores the video data in units of blocks with a size of 1 MB or greater. The tail end of the block is used as a table of contents region for storing table of contents information of a plurality of the most-recent blocks. By providing the table of contents regions at a predetermined frequency, the tables of contents of all blocks being used in the video data area are retained in a distributed and redundant manner. Whenever the power supply is re-activated, the tables of contents regions are read, and pieces of the table of contents information are joined appropriately to construct a complete table of contents in memory.
