DVD Demystified

day before yesterday i got my new DVD writer / reader with CD RW facitlity too. really wondered about DVD, how those techi guys had made out such a large capacity disk to store about 4.3 GB data, which the disk formerly stores 650-700 MB, just 1/7 of DVD. really amazed by the technology. In future, i think the hard disks will be smaller in size which can even hold terra bytes of data and CD’s will hold GB’s of data.
