First Blu-Ray Disc key characteristics...


The Blu-ray Disc using blue-violet laser achieves over 2-hour digital high definition video recording on a 12cm diameter CD/DVD size phase change optical disc.

Large recording capacity up to 27GB:
By adopting a 405nm blue-violet semiconductor laser, with a 0.85NA field lens and a 0.1mm optical transmittance protection disc layer structure, it can record up to 27GB video data on a single sided 12cm phase change disc. It can record over 2 hours of digital high definition video and more than 13 hours of standard TV broadcasting (VHS/standard definition picture quality, 3.8Mbps)
