Abstract:
Management information is provided to control a storage including storage-areas so that each storage-area includes a set of data-areas allocated from each storage-area and each set of data-areas has a data-area size that is a different integer multiple of an access unit of the storage. Logical address information stores information identifying a data-area into which target-data obtained by compressing data has been written, in association with a logical address of the data. Upon reception of the data and the logical address of the data, the apparatus identifies the management information corresponding to a data-area size greater than or equal to a size of the target-data, writes the target-data into an unused data-area of one of the sets of data-areas corresponding to the identified management information, and stores, in the logical address information, information identifying a physical address of the unused data-area in association with the logical address of the data.

Claim (Index 3):
The apparatus of  claim 1 , wherein:\n each of the first and second sets of data areas forms consecutive data areas; the first identification information of the first management information includes a physical address identifying a first head data area that is a data area positioned at a head of the first set of data areas, a first ordinal number that is an ordinal number of each data area from the head data area within the first set of data areas, and the first size; the second identification information of the second management information includes a physical address identifying a second head data area that is a data area positioned at a head of the second set of data areas, a second ordinal number of each data area from the second head data area within the second set of data areas, and the second size; the logical address information stores the target management information, an ordinal number of an data area into which the target data has been written, from a target head data area that is a data area positioned at a head of the target set of data areas, and a logical address of the write data, in association with each other; and upon reception of a logical address within a given size of a read range, the processor, with reference to the logical address information, identifies the target management information and ordinal numbers corresponding to logical addresses within the read range, calculates physical addresses of data areas into which data corresponding to the logical addresses of the read range have been written, based on a physical address of a target head data area positioned at a head of the target set of data areas identified by the target management information, the identified ordinal numbers, and a size corresponding to the target management information, and reads out data at the physical addresses of the storage.
