ABSTRACT:
A signal binary coding circuit and a recording medium reproducing apparatus can binary coding efficiently the input signal sampled by the discrete time, by providing: a subtracting circuit for subtracting direct current components from the sampled value input; a comparator circuit for comparing the output value of said subtracting circuit and a threshold and outputting the binary signal based on said comparison value; an amplitude limiting circuit to amplitude-limit the output value of the subtracting circuit with the fixed value; and a direct current component forming circuit to calculate direct current components from the output value of the amplitude limiting circuit.
