    A disk reproducing device comprising a variable gain amplifier (VCA) (32) that gives a radial push-pull signal including an address signal and an FCM leaking signal to a switch (38). The switch outputs only the address signal to a peak hold circuit (40) based on an FCM mask signal from a mask signal generating circuit (36). The peak hold circuit generates the peak hold signal of the address signal for outputting to DSP (30) that controls a VCA gain based on the peak hold signal. In addition, a radial push-pull signal having gain controlled based on the address signal is given to an address detection circuit (42), and the address signal is detected.
