WORRIED ABOUT YOUR
CD’s LIFE?
Back in 1990s, CDs were new shiny technology with the promise to last
forever. Museums, historical societies, and symphonies started to transfer all types of information onto what was thought as a durable medium: the
compact disc.
The digital age has transformed the way they manage information. Never before it was possible for
humankind to store and record so much information along with great diversity. Even though the data
amounts have ascended exponentially, the life span predicted for the storage media rarely exceeds the
lifetime of a man. For people who are in to collecting as well as leaving a legacy for their descendants, and the ones who depend completely on the digitally stored information, this comes as an enormous challenge.
Now, people are troubled that a lot of important information stored on CDs is on the verge of disappearing. What makes preserving CDs difficult is that they’re not uniform.
The Library of Congress has 400,000 CDs in its collections, from popular music to congressional records. It also gets regular CD donations. Real estate titles and records were also shifted from microfilm to CD in the 1990s across the country.
They simply made the move thinking that anything digital, anything electronic, was going to be much superior and better than everything from the past. Sadly, this thought turned out to
be completely wrong.
With the tight local government budgets most of the people will fail to move to another storage medium in the near
future.
Interestingly, CDs are not being created at all. The record shops selling them are running out of business, and the new
computers aren’t made with CD drives any more. Yet, most of them still have
hundreds and thousands of CDs piled up in our racks and shelves.
Many of the CDs/DVDs, if taken care of properly, can actually last for many years.
Sadly, your favorite CDs, which you play the most, are also the ones most likely to
get damaged.
Optical discs, for commercial purposes, have been available since 1980s. Just in 30 years, a strong volume
of information has been finally collected which tells them the causes of breakage of CDs and DVDs. High progress has also been made in developing material
that can last for longer s pan. The estimations foretell a life time of 200 years for the optical discs. However,
they can never be completely sure when they are about to break. The only thing you can do to save your discs
from damage is to be aware of the factors determining the CD’s life span and the causes behind their breaking.
For understanding what shortens the lifetime of the discs, you must know how they are created. The common thing among all the optical discs is the presence of the three key layers:
• coating layer which guards the reflective layer.• shiny layer reflecting the laser.• polycarbonate disc layer which stores data.
One key factor that affects the maximum life span of the optical disc is the kind of reflective layer. Other
components involve the manufacturing as well as the overall quality of available raw material. The manner
in which the user handles the medium is most important. Managing of optical discs has the most
important impact over its longevity.
