Abstract: PURPOSE: To provide a sector format removed of an ID area for a disk file, which is for recording data of a fixed block system. CONSTITUTION: The disk file is provided with at least one track which is divided into plural sectors. Each sector is divided into a 'servo and restoration' area 30 and data area 32, and a full track number is recorded in a position field 35 within the 'servo and restoration' area. A track start displaying mark is recorded in one selected sector in each track, and a sector start displaying mark is recorded in each of the plural sectors of the track. The number of the sector start displaying marks after the passing of the track start displaying mark are counted to identify a sector. A defective sector is excluded by mapping, through the use of a look-up table.

Abstract: PURPOSE: To prevent the loss of data even when one driven is out of order by storing data in a first to a (n-1)th drives and parity information in an nth drive. CONSTITUTION: A disk storage system includes an array/cluster controller 5 and plural storage mechanism arrays 7-9. The constitution of four (n=4) separated disk files 7a-7d into which the respective arrays are divided is preferable since a half/high disk drive is geometrically matched with an existing shape factor of a personal computer. The array is designed as the subsystem of a direct access storage device, is a system so that the data are stored and fetched at high speed and with high reliability and the data are dispersed between the constituent elements of the system.
