Blue-ray Discs

After learning about the 'DVD War' in which Sony's Blu-ray won against Toshiba's HD-DVD, you might have been wondering what Blu-ray discs are. Well, here are some info about it.

Blu-ray discs are discs developed to enable recording, writing and playback of high definition videos. The discs have an amazing capacity of up to 25 GB on a single-layer disc and up to 50 GB on a dual-layer disc.

A whopping 9 hours of HD video or 23 hours of SD video can fit on a 25GB disc. The basic disc's writing speed is 36 MB per second. The Blu-ray Disc Association is searching for methods on order to get a writing speed of 400 MB per second.

On the whole, Blu-ray is considered better than any other know CD format. This format was developed by the Blu-ray Disc Association along with 180 member companies.
