Blu-ray Disc is the next-generation optical disc format that was developed to enable recording and playback of high-definition video (HD), as well as storing large amounts of data. A single-layer Blu-ray Disc can hold 25GB, which can be used to record over 2 hours of HDTV. Blu-ray uses a blue-violet laser to read and write data while current optical disc technologies such as DVD use a red laser. The shorter wavelengths of the Blu-ray technology make it possible to record more data on the same space.

Be careful with these discs. They seem great when you first get them - they burn just fine and can be read just fine. Hence so many positive reviews, as most people review things straight away.
But then you put your recorded discs away.
Then you dig them out 6 months later.
And NONE of the discs I burned 6 months ago are readable. Not by my PC Blu-Ray drive, nor by my PS3. You can actually see, if you tilt them in the light, how the recording surface has kind of decayed. So do not rely on these for any sort of long term use.
I can only say that these BD-R discs are obviously cheap for a reason!
I'm a university student and had to submit my final work on a blu-ray to be shown in the cinema, the disk failed, then another then another, it only managed to show portions of my film. In the end I sumbited on DVD and it ruined both the video and audio quality on the large screen. Maybe I got a bad batch, these things happen. But if you're planning on using these disks for anything important, DONT RISK IT. Go with a trusted brand and fork out the extra cash, it'll be worth it.
I had 3 failed discs among the last pack of 10. They all failed less than 1 minute into burning. Time will tell if the ones that DID burn successfully will not degrade and lose data. I'm going to try another brand before I go back to this one.
