Abstract :
A magnetic reproducing head using parametric oscillation is discussed. It forms a toroidal core with a closed magnetic path. The head is a flux-response type. The amplitude of the output voltage is independent of the signal frequency and is proportional to the signal field. The head shows excellent reproducing characteristics in a comparatively wide-frequency range
