FIELD: data storage. SUBSTANCE: method in based upon forming information sequence of set of control codes with different length during process of recording and recording of current values of control codes with corresponding lengths when zero or unit subsequences are available. Failures are detected and localized during playing subsequence back. The failures are corrected according to values of control codes formed and decoder and checking of truth of output data is provided according to values of the other control codes formed and decoded. EFFECT: improved precision; improved reliability of operation. 2 dwg
