What's the difference between BluRay and traditional DVDs

As you know Blu Ray was developed by the major electronic manufacturers to store large amounts of data in a tiny space. It enables you to record, rewrite and play video, and manufacturers claim that the quality of it is noticeably better than traditional dvds. Read on to find out some not so well-known secrets about the Blu Ray format, and how you can make a large mistake when buying a player if you're unprepared.

There's many recent innovations, regarding Blu Ray. It originally contained 25GB of data, but it's now possible to record as much as 500GB on a single disc, by using Pioneer's new multi-layer technology. Blu-Ray also has the advantage of supporting much higher speeds of reading and writing. Since the data containing spots are packed more tightly in the disc, it would want less rotation speed, to achieve the same data transfer rate.

The Blu Ray player uses blue-violet laser to read the data - unlike the traditional DVD and CD players, which use a red one. The blue laser has shorter wavelength than the red one, which makes it possible to focus the beam on an even smaller space. This enables the disc to contain more data-carrying spots, and makes it possible to record a lot more data on the same space as a traditional CD.
