The noise reduced disc and the advanced signal reproduction system with the asymmetry compensatory function enhance the disc capacity up to 19.8 GBytes per DVD size. The noise was reduced by applying Aluminum based multi-component alloy for the reflective layer, moreover all the loops in the system accurately function even under the signal asymmetric condition by using the newly developed Error Feedback type PRML. The error rate characteristics versus disc tilts suggest that the ROM disc system has sufficient performance for the practical use.
