TEKNOLOGI BLUE RAY DISC

                                                  Blu-ray Disc – Definition
A Blu-ray Disc is a high density optical disc storage medium, which is used for the storage of all high-definition digital formats like audio, video, and play-station games and so on. They have the same physical appearance as a DVD. The name “BLU-RAY” is actually a combination of the colour “blue” and “ray”. Here blue refers to the blue colour of the laser that is used for its reading and ray refers to the optical ray. While trade marking a product, you are not supposed to include a common or everyday used word. Thus the letter ‘e’ from the word “blue” was omitted.
