The HighDef Wars Have Begun: HD DVD vs. Blu-ray A look at the Next Generation of Optical Burning. A report from BurnWorld.com DVD was introduced back in 1997 when it acquired the …

Technology and Manufacturing Process of Both Formats. It is essential to describe the exact pattern and style of both formats. Blu-ray discs have a tighter track pitch that has the ability to hold more pits than an HD-DVD of equivalent size with a laser of the same wavelength. The tighter track pitch is the result of a single thread of spiral data that continues from the disc all the way out towards the groove. It should be noted that both the formats are using the same type of lasers. The difference lies in the fact that the Blu-ray has different pick up apertures due to a different track pitch. In measurement, the track pitch is equal to 0.65 for HD-DVD and 0.85 for Blu-ray. This makes both the pickups technically insufficient to become compatible. When you come to the surface layer, the HD-DVD is made up of clear plastic on the data surface. This causes unwanted fingerprints and scratches on the disc. HD-DVD has a thicker surface layer as compared to Blu-ray discs and the difference in thickness measures to 0.5 mm. It also cannot be denied that a smaller aperture is better as it enables the laser to get in focus with the aperture. Why Blu-ray is more costly? People who are not equipped with the technical aspects of both the formats are confused why Blu-ray format is the more expensive choice of the two formats. • Blu-ray has a thinner surface layer. Even though, there is an advantage in keeping the data layer closer to the surface, it builds up considerably towards the final cost. • Blu-ray discs also need a special hard coating to protect the data which lies a mere 0.1 mm beneath. All these features contribute towards the final cost. In layman’s terms, Blu-ray is capable of storing more data, but proves to be more expensive when compared with its counterpart, HD-DVD. Conclusion However, it would be too early to state this as none of the gaming manufacturers have given their consent for any of the two formats. The proposal of HD-DVD states that it does not matter at all whether the consumers are getting 30 gigabytes or 50 gigabytes. What matters at the end of the day is, who is offering the latest technology at an affordable price. They further claim that Blu-ray will definitely not be able to slash down the prices of their discs with the continuing production technology because the costs are too high for them. They will have to offer the disc at a much higher price to recover their production costs. So far so good, the best strategy will be to take a back seat, and wait and watch. The winner will come out sooner or later and you never know if both the technologies make an equally good impact in the market. The global market is after all, big enough to accommodate both of them…
