GLOSSARY

Blu-ray: Blu-ray, also known as Blu-ray Disc (BD) is the name of a next-generation optical disc format. The format was developed to enable recording, rewriting and playback of high-definition video (HD). The format is also likely to become a standard for PC data storage and high-definition movies in the future. The name Blu-ray is derived from the underlying technology, which utilizes a blue-violet laser to read and write data. The name is a combination of “Blue” (blue-violet laser) and “Ray” (optical ray). According to the Blu-ray Disc Association the spelling of “Blu-ray” is not a mistake, the character “e” was intentionally left out so the term could be registered as a trademark.
