FIELD: equipment for magnetic recording. SUBSTANCE: method involves storage of information on magnetic carrier as code without correction capacity. When is information is read, second type errors are possible (when carrier signal 1 is read as 0). In some cases such errors in read information is impossible to correct. Errors in coded information are detected by means of difference between adjacent measurements and transition matrix which is preliminary generated and is based on statistic data. EFFECT: increased functional capabilities. 1 dwg, 2 tbl
