Abstract
An information reproducing apparatus for reading and reproducing an angular-modulated information carrier signal which is recorded together with another information carrier signal on a rotating recording disc in a multiplex form comprises pickup means provided in the vicinity of the rotating recording disc for reading the recorded information carrier signals, and demodulating means for demodulating at least the read and angular-modulated information carrier signal. The information reproducing apparatus is further provided with equalizer means between the pickup means and the demodulating means so as to compensate for the frequency characteristics of the pickup means in response to a control signal, and a control signal producing means for producing the control signal representative of the intensity of the extraneous components contained in the angular-modulated information carrier signal which is read by the pickup means.
