PURPOSE: A method for recognizing magnetic link letter is provided to reduce misreading and convenient for division of a letter waveform by obtaining differential waveform about a letter string from the waveform of letter string which a magnetic header obtained and recognizing letter based on the differential waveform. CONSTITUTION: A magnetic header recognizes a character string and obtains character string waveform(S110). An integral waveform of the letter string integrates a waveform value(S120). The integral waveform of the letter string is partitioned into discrete letter waveforms(S130). If the length of the discrete letter waveform is included in a reference range of the letter length, it is confirmed as an interpretation object discrete letter waveform(S150). The letter is read from the interpretation object discrete letter waveform(S160). |
