Thickness of 1.2 mm and the disc is 0.1 mm protective layer.Phase transition is the mechanism for registration.

Signal recording of satellite TV in high definition TV standard, may be his video (1024th), approx. two hours.

Sony Blu-ray player supports reading of DVD-RWDVD-Video and DVD-R, CD-RW CD-R and CD. Reducing block noise and technological frame image with high quality. This technology analyzes the image and adjust to the dynamics. Good image enough to make any system work. Dual Motion Adaptive Interlaced mechanism DMAIPC Image Converter automatically detects interlacing both inputs BS (analog) and a study. If necessary, helps to convert to progressive scan.
