Blu-ray Disc What is Blu-ray Disc?

Blu-ray Disc (BD) is both a new physical disc construction and laser technology, and is the next generation optical playback and recording format following standard DVD and CD optical formats. The physical disc construction and laser system have been significantly redesigned to attain all the enhancements that this new technology offers. The BD technology was specifically design to accommodate High-Definition (HD) content due to its ability to effectively and efficiently store and transfer large amounts of digital data. The name “Blu-ray” comes from the fact that the visible laser is the color blue (actual Blue/Violet). The “e” in the word blue is intentionally omitted because a daily-used term cannot be registered as a trademark. As we go through the following sections you will see that the BD is really an enhanced version of the standard DVD that has been so successful over the past few years. BD and DVD both technologies where designed with two main objectives in mind, high quality video content storage and transfer and interactive functions. The Blu-ray Disc technology was developed by a group of companies (Blu-ray Disc Association BDA) including Sony, Samsung, Sharp, Pioneer, Panasonic, Apple, and LG just to mention a few. In the following sections and chapters we will go into more detail concerning all the Blu-ray Technology enhancements.
