Abstract
A method of managing compressed data including a cache segment generating operation generating cache segments each representing data that is obtained by assembling plural pieces of data requested of writing, and a compressed segment generating operation generating compressed segments each representing data that is obtained by compressing each of the cache segments generated in said cache segment generating operation. The method also includes a compressed segment allocating operation allocating each of the compressed segments generated in said compressed segment generating operation to one or more compression sectors each representing a buffer having a predetermined length, and a compression sector recording operation recording each of the compression sectors, on a disk storage device, to which at least one compressed segment is allocated in said compressed segment allocating operation.
