Abstract

A new playback signal processing system capable of large-capacity optical disc playback of over 25 GB in the same optical format as the Blu-ray Disc has been developed. Generally, as optical disc capacity increases, the readout signal of minimum pits is markedly degraded. The proposed system consists of a Partial Response Maximum Likelihood (PRML) circuit and a waveform correction circuit that controls only the read-out signal of minimum pits. Bit error rate (BER) measurements of the playback of a 30 GB optical disc showed better BER performance.
