The first double-sided Blu-ray Disc production line in China, built at a total cost of 70 million yuan, recently went into operation at the Shanghai Songjiang Industrial Development Zone.
At present, it is also the Blu-ray Disc production line with the highest single line production capacity in the world, utilizing the most advanced technology. It has a monthly output of 500,000 BD25/BD50 Blu-ray Discs, accounting for over 70 percent of the global output.
As the new generation of large capacity information carrier after the DVD, Blu-ray Discs utilize a blue laser operating at a wavelength of 405 nanometres, hence the name "Blu-ray." Internationally, Blu-ray technology has become a universal high definition technology standard, but it is still in the stage of market development.
In Europe and the United States, Blu-ray technology comprises around 10% of the traditional DVD movies market. With Blu-ray technology, a disc with the physical size of a CD can store up to 50 gigabytes of audio and video data, six times the capacity of a DVD. Moreover, it fully supports high definition TV displays and 7.1 surround sound, meeting professional cinema standards.
