SOLUTION: When a disk controller 100 receives an index information adding command and its index information, an external interface part 102 notifies an index information management part 106 of an addition request and transfers information to add the information. Moreover, when the controller receives an index information erasing command, the interface part 102 makes the information management part 106 eliminate information from an index management list in accordance with the index erasing request from the interface part 102. New index information are automatically formed corresponding to the recording and the erasing processing of DV data in the disk controller 100 in this manner to be preserved in the controller.
