The optical path of the DVD system is aligned to that of the HD DVD system to share one sensor area. Experimental results confirm the practicality of the proposed pickup.展开更多

Since the demand for high-capacity media that can record high-def inition movies for an extended time is increasing, HD DVD has been rapidly developed as the next-generation DVD. To achieve downsizing and low power consumption of the LSI, we developed a single-chip LSI which includes an HD DVD signal processing circuit, DVD/CD signal processing circuit and CPU. The new Digital Read Channel provides high readout performance for HD DVD signal which has high inter-symbol interference. A progressed ECC (Error Correction Code) Core contributes to the LSI downsizing.展开更多
