A decode circuit and an optical disc apparatus

A decode circuit of an optical disc apparatus for decoding binary data from a biphase code signal which is reproduced from an optical disc and to be inverted at an end of each bit, said decode circuit being characterized by: correction signal generating means for generating, when an inversion of sai...

Zusammenfassung:A decode circuit of an optical disc apparatus for decoding binary data from a biphase code signal which is reproduced from an optical disc and to be inverted at an end of each bit, said decode circuit being characterized by: correction signal generating means for generating, when an inversion of said biphase code signal is not performed at an end of a bit, a correction signal for correcting the binary data immediately before or after said end of said bit; and data correcting means for correcting the decoded binary data by using said correction signal.
