Before USB storage media (or flash disk as they call it) became popular in the market, CDs and DVDs were the hero of every students and computer addicts. Until now these storage media are still very useful in copying, storing and archiving of data.
But before we get confuse with the terms CD, DVD, CD-R, CD-RW, DVD-R, DVD-RW, Blank CD and Blank DVD let us first define each. CD is short for compact disc while DVD stood for digital versatile disc. Both CDs and DVDs were optical media. Both uses light technology to write and retrieve data. The laser reads and writes data from the center of the disc outward in a spiral direction. CDs and DVDs are identified to designate specific features such as recordability, rewritability, and accessibility. Examples are CD-R (CD Recordable), CD-RW (CD Rewritable), DVD-R (DVD Recordable) and DVD-RW (DVD Rewritable).
Comparing both media, the DVD-R Media is quite popular among consumers. This is because it is a new technology and has a bigger capacity than CDs. Thus many preferred to buy DVD-R and DVD-RW than CD-R and CD-RW. CDs and DVDs were commonly used in almost all libraries for their archives. Some consumers especially students used it in storing their favorite songs and music, games, movies and software applications (projects). Well for me personally I used it as a backup storage. I can’t afford to buy those bigger capacity and expensive HDD, so a Blank DVD-R or Blank DVD-RW will do. Right now I have almost 30 DVD stacks (that is 20 DVDs per stack) in my room. I carefully categorized them by songs, movies, anime, games, applications and e-books. I actually preferred DVD-R when burning files and data when I have my backup every week because of its bigger capacity. I also used Blank DVD-RW aside from USB flash disk when I usually take home some work from the office. But I have to make sure that the office's and my personal DVD Writer are compatible, or else I would have some problem with it.
