ABSTRACT:
An apparatus and method for slicing an RF signal and compensating for the slice level of an RF signal reproduced from a disk, which minimizes a block error rate by optimizing the slice level of the RF signal according to variations in symmetry of the RF signal when slicing the RF signal. A comparator converts the RF signal reproduced from the disk into a digital signal by comparing the RF signal with a slice level, a low-pass filter low-pass filters the digital signal and provides the result to the comparator as the slice level, and a slice level compensator compensates for the slice level provided to the comparator by the low-pass filter according to variations in symmetry of the RF signal.
