8920G Blu Ray Laptops from Acer Aspire

The NEW Acer Aspire 8920G Laptops utilize Blu Ray technology: Blu-ray Disc is an optical disc storage media format now being used in TV peripherals and computers. Blu Ray has many uses; the main ones being high-definition video and data storage. The disc has the same dimensions as a standard DVD or CD.

Blu-ray Disc was developed by the Blu-ray Disc Association, a group of companies representing consumer electronics, computer hardware, and motion picture production. The standard is covered by several patents belonging to different companies. As of March 2007, a joint licensing agreement for all the relevant patents had not yet been finalized.

The name Blu-ray Disc is derived from the blue-violet laser used to read and write this type of disc. Because of its shorter wavelength (405 nm), substantially more data can be stored on a Blu-ray Disc than on the DVD format, which uses a red (650 nm) laser. A dual layer Blu-ray Disc can store 50 GB, almost six times the capacity of a dual layer DVD.

As of April 5, 2008, more than 530 Blu-ray Disc titles have been released in the United States, and more than 250 in Japan.

During the high definition optical disc format war, Blu-ray Disc competed with the HD DVD format. On February 19, 2008, Toshiba — the main company supporting HD DVD — announced it would no longer develop, manufacture and market HD DVD players and recorders,[4] leading almost all other HD DVD supporters to follow suit, effectively naming Blu-ray the victor of the format war.
