<p>The information reproducing circuit has a generating means, having virtually the same frequency transfer characteristic as a recording means, for generating a slice signal (d) whose level is larger than a negative peak level of a signal read out from a recording medium and smaller than a positive peak level thereof, and a comparator (102) for comparing a level of the readout signal (b) and that of the slice signal (f) so as to convert the readout signal into binary digits. The information reproducing circuit cancels jitter, contained in the readout signal, which occurs due to the frequency transfer characteristic of the recording means by using the level variation of the slice signal (d), which occurs due to the frequency transfer characteristic of the generating means. Therefore, a signal read out from the recording medium, even if jitter is contained therein, can be accurately converted into binary digits. Thus, the reliability of the reproduced data can be enhanced. <IMAGE></p> |
