These two formats are heralded as the successor to the current DVD technology. Blu-ray and HD-DVD have both been developed to enable recording, playback and rewriting of high definition video and data. The key to these technologies is the blue-violet laser that is used to write the data to the disc. This blue laser has a much shorter wavelength than the current red laser DVD system, which makes it possible to read and write smaller pits, as a result, these discs can hold up to 15 GB (HD-DVD) and 25 GB (Blu-ray) of data on a single sided single layer 12cm disc.
