System design for double-layer Blu-ray Disc recorders

This paper presents the system design of double-layer Blu-ray Disc recorders built in Philips Research Laboratory. The system architecture, new components, and the advanced signal processing are addressed. The experimental results show that writing HDTV programs to double-layer Blu-ray Discs and reading them back have been achieved. In addition, this paper demonstrates that discs with higher density and higher capacity are possible with the advanced technologies developed.
