So what other feature can Blu-ray offer? Well, the extra capacity (up to 10x that of a standard DVD) as well as inherently advanced interactivity, means that games manufacturers will be able to provide a much richer playing experience and graphic environment. Combine the advanced disc technology with the rapidly increasing bandwidth of broadband services and you have greatly increased possibilities for highly sophisticated network playability. Improved interactivity will not only affect the gamers, however: Blu-ray's inclusion of the Java virtual machine will allow more interactive menus than we have ever experienced, and the ability to overlay additional content from online sources over content on disc can be used for value-added features such as downloading subtitles, movie trailers, web browsing, etc.Blu-ray, so called because of the short wavelength blue laser used to read from and write to these discs, has the higher capacity of the two new formats, at 25GB for a single layer disc, and 50GB for double layer, which means you will be able to record from your TV for longer. In addition to the greater capacity, Blu-ray transfers data slightly faster to and from the player or recorder than HD DVD, which means that your device should feel more ‘responsive'. The reason for this impressive capacity and performance is that the Blu-ray consortium, led by Sony and Apple, decided to create their technology from scratch in order to get the best from a 120mm disc, without being constrained by the limitations of the DVD platform. The slight downside of this decision has been higher development costs and longer lead times, although the consortium is confident of having a full range of product available for customers by mid 2006, with prices comparable to those of HD DVD shortly thereafter.
