The CD Freezer

Summary

We used to think our CDRs would last hundreds of years, but they don't. Recent tests and projections show that, worst case, our precious data and backups may last only a year. What can we do about it?

It has also been shown that these same CDs can last 4 years longer under controlled conditions of temperature and humidity. This is what I aim to build - the CD Freezer, a device capable of maintaining a cold, dry environment independent of outside conditions.

I will capture the process of design and construction as best as I can on this webpage.
