Abstract
A recording apparatus employs a circulating recording scheme for overwriting the oldest recorded data in a recording area having a limited storage capacity with the latest recorded data. The recording apparatus includes a memory device and a data recovery unit. The memory device includes a data recording area for recording data, an index information area for recording index information related to the data recorded in the data recording area, and a reserve index information area provided in part of the data recording area for recording substantially the same index information as the index information. When an error is found in index information recorded in the index information area, the data recovery unit recovers the index information in the index information area based on the index information in the reserve index information area.
