 Q: Exactly why is it called Blueray?
A: This is because Blueray Disc players and PC drives, and also Sony's PlayStation 3, use a blue laser beam to read data from discs. DVDs used a red laser. A blue laser can be focused more tightly, so disc makers can put way more data on a disc the same size as a DVD. A Blueray Disc can hold up to 50 gigabytes, vs a DVD, which holds not as much as 10 GB. With the added space the video can have up to six times the resolution of DVD, plus you get further bonus features and improved surround soundtracks. |
