Abstract :
A new write shift compensation method modified for optical disk systems to which PRML detection is applied is developed. The compensation method achieves optimization of all writing pulses adaptively. The compensation parameters are calculated to minimize the probability of detection errors. The experimental results certify that the ch.bER is improved using this method.
