Blu Ray DVDs were created by the Blu Ray Disc Association. They are called Blu Ray because standard discs are read with a red laser, but the blue ray disc is done with a blue laser.
Why You Should Choose Blu Ray Movies
Capacity: The capacity for these discs for information storage is five times that of the average DVD. You are able to record almost 10 hours of high def video on a Blu Ray DVD, and around twenty three hours of the standard type of videos.
High definition imaging: They offer the viewer a crisp high def video that is not available on regular DVD discs. You are able to rewrite, record, and playback with a blue ray disc, all in high definition. If you have seen a movie on the new Blu Ray Discs then you already know how much better the images look on these innovative optical discs compared to standard DVDs.
