ABSTRACT:
The present invention provides an optical disc reproduction method and an optical disc reproduction apparatus capable of accurately extracting a BCA code without being affected by mirror modulation of an RF signal.
An RF signal is peak-held via a buffer consisting of an operational amplifier according to time constants of a capacitor and a resistor. This RF signals subjected to low pass filter processing by the capacitor and the resistor prior to a predetermined binarization, thus enabling extraction of a BCA signal form the aforementioned RF signal.
