What is Blu-Ray?

Blu-Ray is a new DVD format being developed by some of the key businesses in the electronic and entertainment industries.

The main advantage of Blu-Ray DVDs over the current DVDs is that they can hold 25GB of data and can be used for recording and playing High Definition television.

The current DVDs use a red laser to read the discs, but the new format uses a blue, purple laser.

25GB may sound like a lot of data compared with the current size of DVDs, but with the higher expectations of consumers for increased sound and vision, increased data storage abilitity will become a necessity.
