Abstract
A file management system including a hard disk unit and a file management unit. The file management unit manages data to be read and written from and into the hard disk unit such that data in a file is continuous in a predetermined logical address space and specifies a target data requested to be read and written from and into the hard disk unit by a predetermined logical address within the logical address space. The hard disk unit performs processing of reading and writing data after translating the predetermined logical addresses specifying the data requested to be read and written into LBAs. Then the hard disk unit performs defragmentation of data recorded on a magnetic disk based on the predetermined logical addresses.
