We proposed a new signal quality evaluation method applying a sequenced amplitude margin (SAM) for over 30-GB Blu-ray discs (BDs), where the dominant error pattern differs from lower-density discs (23–27-GB BDs), and conventional signal quality evaluation method such as maximum-likelihood sequence error (MLSE) lose accuracy. We experimentally confirmed the effectiveness of our new method for 30–31.5-GB BDs.
