Blu-ray technology takes its name from blue-violet laser that it utilizes for read/write operations. The CD and DVD disk technologies use red laser beam. Sony is offering dual and single-layered Bluray discs that are available in BD-RE (rewritable) and BD-R (recordable or write-once) formats. Sony dual-layer Bluray disc can accommodate 50 GB data. This is almost 10 times greater than a traditional DVD optical disc. A 50 GB Blu-ray disk can record SD (standard definition) video of 23 hours and 9 hours of HD video.
The wavelength of red laser used with CD and DVD technology is 65-nanometer. The 45 nanometer blue-violet laser enables the Blu-ray disk to house more volume of data within the same physical disk area. The Bluray media disk uses the optical storage space more efficiently, while retaining the same physical size of CD and DVD disc. Other market leading Bluray disk brands are Imation, Maxell, TDK and Verbatim. Sony Blu-ray disks and their part numbers are:

The video quality of Bluray media delivers more depth, colors and is much sharper than the DVD recording. Blu-ray outshines the DVD recording in sound quality as well.
DVD video recording delivers up to 5.1 surround channels, whereas the Blu-ray disk features an exceptional 7.1 surround channels.
