Blue Ray, blu ray, Blu-Ray – is often misspelled (Blu-ray disc is the correct, full name – BD for short). Regardless of the spelling Blu-ray is the future of the optical disc, offering a full five times more storage capability than a DVD and even more than that sometime in the future.
Blu-ray discs were developed to synch up with and support the extremely high quality of picture and programming being offered by high definition televisions (HDTVs). DVDs simply do not offer enough storage capacity for this futuristic medium and something with more versatility had to be developed to fill the void.
Blu-ray is expected to completely replace DVD, but the two will co-exist into the future until HDTVs become less expensive and more prevalent. Most Blu-ray disc players also support DVD playback so your existing DVD collection (and DVD burning software) isn’t in any danger of becoming obsolete (like, for example, laserdisc). Some will also have CD capability.
