Abstract

In order to realize 15/27 GB Read-Only disk system using blue laser, new signal processing is required. We have realized 15/27 GB system by using the 2 dimensional adaptive equalizer. The 2 dimensional equalizer was composed of the cross-talk cancel system, the asymmetry compensation type tangential adaptive equalizer and the limit equalizer. By using these signal-processing systems we could reduce the bottom jitter more than 3 % and we could expand the tilt margin.
