Today’s rapid diffusion of HD broadcasting along with burgeoning volume of digital data has increased the demand for high capacity optical disk media that offer faster recording speed and larger capacity. Blu-ray is the next generation of high definition video format that meets all the emerging demands of the HD broadcasting. Blu-ray disk format has been poised to replace the DVD disk media.

Sony is no doubt the world’s leading company in recording media, consumer electronics and backup storage technologies. Philips and Sony are the primary developers of the Bluray disc technology, whereas the list of supporters is also very lengthy. Nine consumer electronics companies, Sony, Samsung, Sharp, Hitachi, LG, Thomson, Philips, Pioneer and Matsushita founded Blu-ray association in 2002.

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:

BNR50RH, Sony 50 GB Blu-ray recordable disk
BNE25RH, Sony 25 GB Bluray re-writable disc

The I.T companies supporting the Bluray format are HP, Sun Microsystems, Dell and Apple computer. Video resolution delivered by the Blu-ray disk technology is 1920x1080, whereas the DVD video recording can only manage video resolution up to 720x480. 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. As the high definition DVD is fading out of sight, the Blu-ray disk technology has become the industry leader in optical disk media.
