Standard DVDs VS the Blu Ray Disc
There is this thing called the Blu Ray disc, the next thing to come next after the DVD. Standard DVDs came in to "out-store" the CD which could store 700 megabytes of data storage space. Standard DVDs could store up to 4.7 gigabytes of data, with dual-layer DVDs capable of storing up to 8.5 gigabytes of data storage space.
This space could be utilized in storing personal computer data files such as Microsoft Word Documents, PDF eBooks, and other personal computer data including program applications and personal computer games. This same space and DVD medium could be utilized in distributing movies, as well as other multimedia formats like audio files and/or compressed audio files like mp3s.
Blu Ray discs come in to truly "out-store" standard DVDs, as a Blu Ray disc could store up to 25 gigabytes of data, with dual-layer Blu Ray discs capable of storing up to 50 gigabytes of data. The contents of five standard DVDs could be stored into one Blu Ray disc, the truly impressive thing about Blu Ray discs.
The impressive storage capacity of Blu Ray, paired with the advanced utilization of audio and video codecs, makes Blu Ray the ideal medium for High Definition movies to be distributed in, or recorded in, something which couldn't be done with standard DVDs the way it could be accomplished in Blu Ray discs.
Blu Ray is named as such because of the blue hued laser utilized in its successful operation. As blue light boasts to have shorter wavelengths, it enables Blu Ray the possible data reading process to have greater precision. Standard DVDs and CDs utilize a red laser for their successful operation.
Just like standard DVDs, Blu Ray discs come in formats ideal for whatever users would have need of them. There is the BD-ROM, the BD-R and the BD-RE, which are basically the same format concepts of standard DVDs. The BD-ROM is the read only class of Bu Ray disc formats, perfect for the distribution of High Definition movies, personal computer software, and personal computer games, and games for game consoles. The BD-R would represent the DVD-R class of standard DVDs, ideal for recording data files of software and games, as well as High Definition movies. The BD-RE is the rewritable class of Blu Ray, capable of being rewritten with data, and used more than once.
When talking about standard DVDs VS Blu Ray discs, Blu Rays truly out-store standard DVDs by a mile.
