This project is about the significance of the newly emerging Blu-Ray compact disc format. Thanks to developments in the spacing of tracks and track width, this new format is able to store much more than previous formats. A traditional CD can store about 800 MB of data, a DVD 4.7 GB, but the Blu-Ray can store 25 GB on single layer format, or 50 GB on a double layer.
The primary reason the format is capable of achieving much narrower track width's is because of the wavelenght of the laser used for reading and writing to the disc. The wavelength, 405nm, not coincidentally a blueish violet colored laser dictates a much narrower track than the 650 nm wavelength of the red laser used for reading DVDs.
Because of those reasons, the Blu-Ray format is an increasingly popular format for HD video and large storage size optical discs.Like the cubist background? Get it?
