Abstract:
1. A method for magnetic character recognition comprising: preparing standard array data of peak intervals, out of an array pattern of a plurality of intervals between peaks that are included in a standard character waveform of each magnetic character, in accordance with a standard waveform that is used as a datum for reading a character string, including a plurality of magnetic characters printed with magnetic ink, by a magnetic head; 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 ofpeak 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 a highest coincidence wherein, when a peak has intensity greater than a specified intensity level within a range for one character, the segmenting a character waveform further comprises judging whether a part of the regeneration waveform is dealt with as a character region or a region with no signal.
