100 films in one CD

Compact disk was the core storage contrivance few years ago. Then DVD replaced them with advantage of having more memory space inculcated in it. But the CD is again on track since at present we can accrue more than 100 movies in a single disk with the availability of holographic digital storage. This startling technology is now under development and it will be available for use in four years. The entailed data is stored in layers in the disk facilitated by split laser beams and in contrast to the today’s work it is not just stored on the surface. A single compact disk can store around 1 terabyte of data that is equivalent to 110 film DVD’s. Thus now we can keep all our collections namely film, emails, music and pictures embedded in a single disk.
