Blu-ray vs HD-DVD - the lowdown on the fighting styles

The current goal of Blu-ray and HD-DVD is fast as much public assistance, how it ultimately the consumer who will decide which format above comes out. With the Association talks it's otherwise you, decide which format to adopt. The truth about each format as below is to help you with this difficult decision.

History the Blu-ray-format's head company Sony and Philips with Toshiba, and Hitachi are heading the HD DVD format. This situation is not the first time where these two pages each other go with contrasting styles. The DVD format was born disc (SD) (MMCD) and super density from the cooperation of the multimedia CD-ROM Sony/Philips Toshiba. Although it ended for the consumer with the DVD format, which are widely accepted and becoming the new standard, it was Toshiba's camp, which came from above on royalties.
This led to work on new formats from both sides with Sony that some with the aim of which regain its lost market. The two projects have been although production but not really going anywhere at the time. Sony Professional disc for data (PDD) is the Blu-ray format during Toshiba's advanced optical disc always HD-DVD. This brings us back to the original situation where there are two competing formats with an association, that look very much less likely.

Technical both Blu-ray and HD-DVD use a wavelength of 405nm, but the smaller track pitch on Blu-ray (see Blu-ray disc) to learn to be compressed and offers greater capacity. However, it is the different track pitch that makes these two formats incompatible. The surface layer of the two differ also like HD DVD a 0.6 mm layer DVD similar uses, while the Blu Ray uses a 0.1 mm clear plastic layer.
This difference is the main reason why costs are higher with Blu-ray. Costly production methods requires the discs must be applied to make and to make a hard coating to the discs accordingly resistant against dust and fingerprints.

Capacity Blu-ray offers currently 25 gb for single layer and 50 gb dual-layer discs. But TDK working on a 200 gb disc has begun the 6x33gb is layers.
HD DVD comes in 15 gb for single layer and 30 gb dual layer. Tests have reached best so far 45 gb but the theoretical limit is 60 gb. This shows that the maximum for HD-DVD only 10 gb more than what can already offer Blu-ray.
