What is Blu-ray?
Blu-ray also known as Blu-ray disc (BD), is a next generation format developed to deliver High Definition video content and or large amounts of data.

Where does the name Blu-ray come from?
The name Blu-ray refers to the laser used to read the disc. A BD uses a shorter wavelength blue laser as opposed to the red laser used for SD DVDs and CDs.

How does it work?
Larger capacity on Blu-ray discs is achieved through the use of a shorter wavelength laser as opposed the larger red laser used on SD DVDs. The blue laser allows BD to utilize smaller pits and lands than are used on SD DVDs. Pits and lands are the method by which information is stored on an optical disc. Because the pits and lands are smaller they can be placed closer together resulting in more information being stored on the same size disc. In conjunction with different optics and faster disc rotation, BD discs can store 5X more data than SD DVDs.
