Abstract
A method for demodulation where a plurality of preliminary data rows for creating the demodulated data are created according to intervals, each of which is a interval between peaks in a read signal coming from a magnetic head. Each preliminary data row includes first individual data identified according to the intervals, wherein a plurality of bits constitute the first individual data. At the time of creating the preliminary data row, standard intervals are identified for judging a first individual datum to be either '0' or '1', and the standard intervals are assigned in a template saved beforehand. Then, intervals for judgment are compared with the standard intervals assigned in the template, with respect to each bit of each bit patterns. A bit pattern in relation to the preliminary data row is identified according to the comparison result, in order to set the preliminary data row with the identified bit pattern.
