DVDs, which stand for either digital video disks or digital versatile discs, are high-density optical disc storage units. This type of optical disc storage units can carry not only video and audio files but also computer data. Patterned after compact discs (CDs), DVDs share the same size as CDs, but their data capacity is five to ten times bigger than CDs. The types of DVDs that are obtained or downloaded without an exchange for a fee are aptly called free DVDs.
Who invented DVDs?
The idea and development of DVDs can be credited to the collaboration of Sony and Philips. The two media conglomerates agreed to collaborate in the development of an optical disc storage unit that will not only incorporate the CD-ROM technology but will also replace VCDs, laserdiscs and VHS tapes.
What do free DVDs contain?
The types of programs contained in free DVDs include movies, TV series, concerts, video games, music files, animations and text files. Most free DVDs are inclusive of interactive menus that resemble those of CD-ROMs. These menus are operated either via computer mouse or DVD player clickers.
What is the capacity of DVDs?
Typical free DVDs can hold up to 17 gigabytes of information on both sides of the disc. They can contain video files, audio files and other digital information. Free DVDs of the mini DVD variety, which are about 80mm in diameter, can hold only 1.4 gigabyte worth of data. This variety of free DVDs are not capable of containing full-length movies because of their 30-minute video capacity.
