DVD-RW and Blu-Ray discs offer backup

Music, photos, videos, etc can be stored on a CD or DVD. A CD or DVD is, thus a storage device that can be used to store any kind of content – video, audio or written. Pictures taken on a camera can be transferred to a computer and can then be stored on a DVD. Nowadays, DVDs are most commonly used as a backup medium for any kind of data. Such DVDs, once written, cannot be used for further storage of data.

However, a DVD-RW can be used for repetitive data storage. These DVDs can be re-written. A DVD-RW is basically a re-writable DVD where you can store data, remove it and store some new data. A DVD-RW is a good way to save your money if you are buying CDs or DVDs frequently.

With the advent of Blu-Ray discs, DVD technology has reached new heights. Such a disc allows data storage six times greater than a DVD. A video format different from DVD, Blu-Ray discs are used for high definition videos.

However, one should always understand that the maker of a movie, game, or music album possesses the copyright on their work, so it is illegal to copy it and distribute it. We should fight piracy and the illegal duplication of any content.
