ABSTRACT:
A digital signal reproducing apparatus includes a reproducing circuit for reproducing from a recording medium a signal, whose amplitude takes on plural values, and which was recorded on the medium by digital modulation of a pilot signal component with digital data, a forming circuit for forming binary data indicative of the plural amplitude values, and a detecting circuit realized by binary data processing circuitry and detecting the pilot signal component on the basis of the binary data.
