PURPOSE: A multiple disk system and its control method is provided to control a plurality of disk stubs managing each disk, generate a logical cylinder by conceptually integrating cylinders of the physical disk into one logical cylinder, and enable a logical controller to store data with a locality in the logical cylinder so that it can enhance a speedy access and a storage capacity. CONSTITUTION: The device comprises a logical controller and a plurality of disks. The logical controller, as a system software, generates a logical cylinder on each disk, and generates logical partitions for a file system based on the logical cylinder. The file system is installed on the logical partitions. The logical controller includes a disk stub, and controls each disk via the disk stub by using a kernel thread. The logical controller offers a single disk image comprising logical cylinders with a serial disk block number. The disk stub, corresponding to each disk, is a disk controller implemented based on the kernel thread.
