Everything About Different Types Of DVDs
DVD, the shortened term of Digital Versatile Disk is very popular today when it comes to portable data and movie storage. Big companies in Electronics industry Philips, Sony and Toshiba launched it in 1995. And soon it replaced the CD and VHS technology as it's capable to save more than seven times the data that can be stored in a CD. You will find several variations of DVDs. Mostly what we see today are DVD-R and DVD R types. But new models are arriving such as HD-DVD and Blue Ray DVD.

DVD R and DVD-R both are one time writable optical disk. Both are equal in capacity, that is 4.7 gigabytes. However, DVD-R is supported by the vast majority of the players and also is supported by DVD forum (The group of all software and hardware providers related with DVDs).
