Default Re: Digital? Great?

After you've burned your photos to a CD, it's a good idea to keep the CD itself in a dark area. Tests have shown that the dyes in CDs, both CD-Rs and CD-RWs, degrade over time. Some tests showed that in as little as two years, a CD exposed to light had 10% of its files corrupted. Many professional photographers who back up to CDs now back up the CDs every year or two so there's little chance of the CD degrading over time.
Another issue is how long the actual data storage method will last before it's obsolete? When CDs first came out, they were touted as being able to last indefinitely, and while - if handled correctly - a CD could last well into the future, would the technology to read the CD be around in 50 or 100 years? Or even 20 years? If you have data stored on a 5-1/4" floppy disk from the 1980s, it's doubtful you could find a computer today to access the information.
Not to sound doom and gloom, but if you're not printing your pictures on archival paper with probably a dye-sublimation printing process, you will need to keep abreast of new data storage technology as it gets into the mainstream, and transfer your photos to each new generation of media.
