ABSTRACT:
An apparatus, a method, and a computer readable recording medium thereof to update filter tap coefficients of an equalizer include a defect signal detection unit and a coefficient updating unit. The defect signal detection unit receives a sampled input signal reflected from an optical disc and/or a track jump signal, detects whether the input signal and/or the track jump signal are defective, and outputs an update stop signal indicative thereof. The coefficient updating unit stops the updating of the filter tap coefficients in response to the update stop signal and outputs current filter tap coefficients.
