Abstract
A magnetic card recording apparatus records information with a desired predetermined high recording density on a magnetic card moving at a varying speed. The apparatus comprises guide means for guiding a moving magnetic card, a magnetic head disposed to contact with the magnetic card moving through the guide means, an electric signal generator having a movable member moved in response to the movement of the magnetic card, a voltage signal generator for receiving the output signal of the electric signal generator to generate a voltage signal of a magnitude proportional to the moving speed of the magnetic card, an oscillator oscillating at a frequency proportional to the magnitude of the output voltage signal of the voltage signal generator, a converter for converting an input information signal on the basis of an output signal of the oscillator, and a writing controller for controlling the recording of an output signal of the converter on the magnetic card.
