Will our digitized works of print be subject to the ravages of time? The question
looms large as newer ways to protect data spring up

It may be presumptuous of us to link our holiday snaps with cultural works of art and human history, but these mediums face a similar dilemma, that of erosion with time. After more than 20
years, our highland landscape pictures will no longer hold the lush greens, and our prized once-in-a-lifetime snap that warrants artistic merit would have faded and would have lost its luster. In our libraries, many written works are vulnerable to fading, tinting and general wear and tear. The recent flurry of media transference (to electronic backup) has brought about issues of longevity (apart from criticisms over copyright and version/edition control). It is still
an imprecise science to measure the lifetime of a CD, as it would invariably be subjected to wear and tear before its 100- year storage integrity can be verified. Also, conservative estimates have narrowed the longevity of CD-ROMs to between five and 10 years.

Every year, the world produces more than 1 million gigabytes of information stream only 0.003 percent of which originates from written or printed works. A large portion of the information
consists of photographs, animation, video, audio, graphics and various
amalgamations of multimedia. Many of these works are of cultural importance and should be preserved for our future generations.

There are several other storage options becoming viable down the line. The capacity offered by HD is insignificant when compared to the holographic storage media under development. The American developer InPhase has declared that it can store up the 1.6 terabyte of data on a piece
of holographic media. With that kind of storage capacity, four million books from a library collection could easily fit into one of these media.

The first holographic disc which has a capacity of 300 GB will be released in the market this year along with its reader/writer. The exterior case reminds us of the older design. The datas media is covered with a case that has a diameter of 5.25-inches, similar to a an old floppy disk...
