Title: Apparatus and method for full period compensation in an optical disk reader

Abstract: An optical disk reading apparatus and method compensate for errors in the full period of an EFM signal. An RF amplifier converts an optical signal reflected from an optical disk into an analog electrical signal. A signal converter converts the analog signal into a digital signal which is modulated to provide an EFM signal. A full period compensating portion compensates for full period errors in the EFM signal and outputs the error compensated EFM signal. An error correcting portion corrects the errors of the compensated EFM signal using an error correction code. Image quality is improved by removing the full period errors.
