Magnetic information processing device and magnetic information processing method

A magnetic information processing device for use with a magnetic recording medium storing a magnetic signal, the magnetic information processing device comprising:

• a magnetic card detection unit comprising a sensor and being structured to detect insertion of the magnetic recording medium and output a medium detection signal indicating whether the magnetic recording medium is inserted;
• a magnetic head structured to read the magnetic signal recorded in the magnetic recording medium, and output the magnetic signal as an analog signal;
• a signal detection unit structured to amplify the analog signal output from the magnetic head, and output a detection output signal when the analog signal exceeds a predetermined threshold value of a magnetic detection sensitivity;
• and
• a judgment unit structured to:
• receive the medium detection signal and the detection output signal;
• identify the detection output signal as different from the magnetic signal stored in the magnetic recording medium in response to the medium detection signal indicating that the magnetic recording medium is not inserted;
• and
• output the detection output signal in response to the medium detection signal indicating that the magnetic recording medium is inserted.
