For all those science-y types in the house, here's a painfully simple overview of how Blu-Ray works and what it can do.
- Blu-Ray gets its name from the type of laser used to read this discs. Blu-Ray discs are read using a blue laser (duh), as opposed to the traditional red lasers of yesteryear. Because blue lasers operate on a shorter wavelength than red lasers, data on a Blu-Ray disc will be readable even if densely stored. This is what allows a single-layer Blu-Ray disc to hold 25GB of data, or roughly 35 times the capacity of a standard CD.
- Blu-Ray movies can be played at either 720p or 1080p resolutions and are natively encoded with Dolby Digital DTS surround sound for the best in audio and visual quality.
