  • Patent number: 9218846
    Abstract: A demodulation method of magnetic data may include a first data creating step which creates a preliminary data string for creating the demodulation data on a basis of an interval that is a time interval between peaks of a read signal of an analog-shaped magnetic data, and a second data creating step which creates a demodulation data creating data for creating the demodulation data on a basis of the preliminary data string created in the first data creating step. When a peak of the read signal is not detected for a predetermined time, a pseudo-peak is generated and a pseudo-interval is stored in a data storage section, and steps similar to the first data creating step and the second data creating step are executed, and the pseudo-peak is generated until the demodulation data creating data corresponding to a final interval is created.

  • Patent number: 8701995
    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.
