Abstract
An information reproduction apparatus for reproducing a frequency modulated signal, the information reproduction apparatus having a demodulation portion for demodulating the frequency modulated signal and a deemphasis portion for deemphasis the demodulated frequency modulated signal, comprises: a detection portion for detecting an inversion of levels of the demodulated frequency demodulated signal to produce an inversion detection signal, the inversion being such that the frequency demodulated signal is uncorresponding to the frequency modulated signal when the frequency modulated signal having an image of an edge portion; a compensation portion responsive to the inversion detection signal for compensate the demodulated frequency modulated signal, the compensated demodulated frequency modulated signal being supplied to the deemphasis portion. The apparatus may further comprise a dropout detection portion for detecting dropout of the demodulated frequency modulated signal to produce a dropout detection signal in the presence of the inversion detection signal and the dropout compensation portion responsive to the dropout detection signal for compensating the demodulated frequency modulated signal.
