The Line of Blu Ray Discs and Blu Ray Dual Formats
In 2006 the Blu Ray disc was shown to the world, and stands to be the next thing to replace the standard DVDs which are now in circulation. Not that there is anything wrong with the DVD line of optical discs, Blu Ray discs just show to have more promise, as Blu Ray discs are capable of storing quite vast amounts of data figures, with its impressive storage capacity. This "extra space" is pretty much what made the DVD the best "replacement" against the CD in the first place, and stands to be the strong point for Blu Ray discs.
CDs could store up to 700 megabytes of data. DVDs could store up to 4.7 gigabytes, not megabytes, of data, while Blu Ray discs, or BD, could store up to 25 gigabytes of data. The contents of five DVDs could be stored in one Blu Ray disc, easily. This large capacity value also enables, through the combined application of video and audio file codecs, the easy recording of High Definition video formats, which pave the way for an impressive movie watching experience.
Blu Ray dual format discs even stand to be more impressive, as 50 gigabytes of storage space is boasted in them. A Blu Ray dual format disc would basically have the storage power of a desktop computer system's 40 gigabyte hard drive or 60 gigabyte hard drive, which users or manufacturers could fill with all sorts of data congruent to what they want.
Blu Ray technology utilizes a blue-violet hued laser, thus its Blu Ray name. Standard DVDs and CDs utilize red hued lasers. Blue light, having a shorter wavelength, allows Blu Ray media to be read with greater data precision capacities. Blu Ray discs and Blu Ray dual format discs come in the same three formats DVD and CD media come in. There is the BD-ROM, the BD-R and the BD-RE.
The BD-ROM is pretty much the read only class of Blu Ray discs, which is ideal for the distribution of movies, software for personal computer systems, and games for pc and/or gaming consoles. Blu Ray dual formats or single-layer formats could be found as BD-ROMs. The BD-R is the recordable, or writable class of Blu Ray discs, which could come in the Blu Ray dual format as well. The BD-RE is the rewritable class of Blu Ray discs, meaning these could be written with data, erased, and rewritten again.
Having read these things about Blu Ray, is it still a wonder why it is hailed to be the DVD replacement that it is sure to be?
