Abstract

PURPOSE:To shorten the retrieval time by utilizing track codes recorded in a data recording part as the target retrieval. CONSTITUTION:Sector number recording parts 18, 20..., 26, 28 are provided respectively to each sector of tracks 12, 14 and 16. In the track 12 between the sector number recording part 18 and the next sector number recording part 20, auxiliary track number recording parts 30 and 32 are respectively provided in two places, where four bits in lower order of each of the sector numbers of the track 12 is recorded respectively. By this method, since the target track can be confirmed even in between the sector number recording parts, the latency time of the disk is reduced, so that the quick retrieval can be carried out in a short time.
