(57) ABSTRACT

A method for magnetic character recognition may include preparing standard array data of peak intervals; generating a regeneration Waveform out of a character string of magnetic characters printed on a surface of an information data recording medium; segmenting a character Waveform of each magnetic character out of the regeneration Waveform; generating array data of peak intervals out of an array pattern of a plurality of intervals betWeen peaks that are included in the character Waveform; and comparing the array data of peak intervals With the standard array data of peak intervals; Wherein, based on a comparison result of comparing the array data of peak intervals With the standard array data of peak intervals, a read character is identified With a character corresponding to an array data of peak intervals that shoWs the highest coincidence.
