Abstract

PURPOSE:To reproduce recorded information signal without dropping S/N in a simple structure with high fidelity by comparing the levels of two auxiliary signals signals separated from a reproducing signal and controlling the tracking of the magnetic heat for reproduction by using such comparison output.
