    • In order to perform processing of analyzing card data in an appropriate amount of time depending on the number of tracks actually present on a magnetic stripe with use of a single demodulation circuit, the single demodulation circuit produces, based on magnetic data read by a magnetic head, a single common card running signal obtained by ORing card running signals of tracks present on the magnetic stripe of the magnetic card, a clock signal of each track present on the magnetic stripe, and a data signal of each track present on the magnetic stripe. A card running signal generation circuit generates, based on the common card running signal and the clock signal of each track, an individual card running signal of each track present on the magnetic stripe. A data analysis processing unit determines, based on presence or absence of the individual card running signal, presence or absence of a track on the magnetic stripe to perform processing of analyzing the data signal only for the track determined to be present on the magnetic stripe.
    • 为了根据使用单个解调电路在磁条上实际存在的轨道的数量,在适当的时间内进行分析卡数据的处理,单个解调电路基于由磁头读取的磁数据 通过对存在于磁卡的磁条上的磁道的卡运行信号,磁条上存在的每个磁道的时钟信号和存在于磁条上的每个磁道的数据信号进行OR运算获得的单个普通卡运行信号。 卡片运行信号产生电路基于公共卡运行信号和每个磁道的时钟信号产生磁条上存在的每个磁道的单独卡运行信号。 数据分析处理单元基于存在或不存在单独的卡运行信号来确定磁条上是否存在磁道,以执行仅针对确定存在于磁条上的磁道来分析数据信号的处理。
