Title:
DATA STORAGE DEVICE, METHOD, PROGRAM AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/189784
Kind Code:
A1
Abstract:
The present invention makes it unnecessary to separately provide a specific device for detecting a state when controlling an operation by a storage unit that stores data. A data storage device comprises: a first storage unit; a second storage unit; and a determination unit that determines if data of at least a portion of a first data block stored in the first storage unit satisfies a predetermined first criterium. The determination unit transfers and stores the first data block to the second storage unit if the first data block satisfies the first criterium, and also transfers and stores to the second storage unit a predetermined number of data blocks stored in the first storage unit following the first data block. If there is data satisfying a predetermined second criterium in the predetermined number of data blocks following the first data block, the determination unit continues storing, to the second storage unit, the data blocks stored in the first storage unit following the predetermined number of data blocks. If there is no data satisfying the predetermined second criterium in the predetermined number of data blocks following the first data block, the determination unit stops storing, to the second storage unit, the data blocks stored in the first storage unit.
