What is Blu Ray?

You've heard about High Definition (HD) television and discs, but have you heard about Blu Ray discs? Blu Ray discs are high-density discs formatted to store high definition data. Basically Blu Ray discs can hold much more data than a typical burnable DVD because Blu Ray discs are burned with a blue-violet laser. Blue rays are characterized by a short wavelength which allows these discs to hold more data. A typical Blu Ray disc can hold about 5 times the data of a regular DVD.
