A demodulation method for magnetic data may include the steps of reading magnetic data with a magnetic head, generating a digital signal from a read analog signal, comparing an inversion time interval of the digital signal with a bit reference time interval, and generating bit data on the basis of comparing result of the digital signal. This demodulation method for magnetic data may further include a first step of comparing the inversion time interval of the digital signal with a bit lacking reference time interval which is set to be longer than the bit reference time interval, and a second step of discontinuing generation of the bit data when the inversion time interval of the digital signal is detected to be longer than the bit lacking reference time interval in the first step.
