Blu-ray disc is the most advanced replacement for CDs and DVDs. Since Toshiba stopped the production of HD-DVD, the only competing product of Blu-ray in the market, it has got a significant monopoly in the international market. By surpassing HD-DVD, Blu-ray has proved that it is the best technology in the industry till date. The consumers can now invest their cash with trust and confidence in Blu-ray.
Although DVDs or CDs are quite like Blu-ray, but one of the significant differences between the two is that Blu-ray uses blue-violet beam instead of traditional red laser beam. In fact, Blu-ray derives its name from this. The blue laser beam, technically speaking, has a shorter wavelength if compared it to the red one. This efficiently increases the storage capacity of the Blu-ray disc by allowing the information to be more concisely packed.
As a result, the additional information needed, as per the requirements of HD TV, can be easily injected into the disc and hence, the consumer can take pleasure of the high quality movies on their big LED and LCD TV sets. The additional disc space allows the disc-makers to inject alternative endings, interviews, cut scenes, games etc to their respective Blu-ray discs.
Blu-ray discs have a huge storage space. A dual layer Blu-ray disc can store around 50GB of data and a four layer disc can store around 100GB of data. Many companies are working upon 200GB discs and 250GB discs are under research.
Blu-ray discs cannot be played on normal CD or DVD players. A special Blu-ray player is required to run these discs. Many Blu-ray disc player Manufacturers and Suppliers are designing them in such a way that they are capable of running all CD, DVD and Blu-ray discs.
