Abstract
PURPOSE: To reduce the retrieval time delay of index information and to decrease the retrieval time of video information, by recording a plurality of sets of the same index information on index recording tracks.
CONSTITUTION: Since the amount of recording for index information is very less for an index recording track 71 to the amount of recording of video information, the index information with equal contents is recorded for a plurality of number of times. That is, the same information of each item block 26 is, for example, recorded sequentially six times. Thus, the 1st item block is recorded at the location of the block numbers 2, 44..., and the 14th item block is recorded at the location of 41,...,251. Thus, the retrieval time delay of index information accompanied with the code error due to the effect such as dropout can remarkably be reduced, allowing to decrease the video retrieval time.
