FIELD: information technology.
SUBSTANCE: method of restoring records in a storage device, in which, when recording data into information areas of the storage device, its corresponding control areas are populated with at least two reference control sums calculated using predetermined formulas, and when using the storage device, current control sums are calculated multiple times using a computation unit and using the same formulas for each set of codewords with identical numbers in all information areas and each of the calculated current control sums is compared with the corresponding reference control sum to find the error syndrome and replacing the detected errors in records with correct values.
EFFECT: high rate of computation during disc recovery.
