摘要： An asymmetric error correction device includes an analog-to-digital (A/D) converter sampling analog radio frequency (RF) signals reproduced from an optical disc with a sampling period, converting the same into the digital sampling signals, and outputting the same; a signal detector for detecting 4T sampling signals varying in polarity thereof every four times the sampling period among the digital sampling signals; an operator selecting and adding a signal among the 4T sampling signals to operate an asymmetric error value; a counter cumulatively counting the asymmetric error value operated in the operator; and a corrector correcting a signal level of the digital sampling signal outputted from the A/D converter if the counted value counted by the counter is out of a predetermined critical range. The asymmetric error is precisely corrected even in a signal part in which the asymmetric error is minutely generated.
