Fear not, disc rot is all but inevitable. Experts caution enthusiasts to consider how and where they store their disc collections. Of course, pinpointing the ideal storage conditions can be difficult, and often depends on the type of disc. However, several universal precautions can help shield your collection from unnecessary damage. Store your discs inside cool, well-ventilated rooms and away from direct sunlight. Keeping discs in their individual storage containers can help reduce exposure. Some enthusiasts suggest that collectors store the booklets and other paper materials in a sleeve on the outside of the case, as the paper can create moisture on the disc overtime.

However, such concerns are minor and likely won't have a major effect for most users. Critically, the shape of your storage unit makes little difference, with both vertical and horizontal storage systems having no measurable effect on disc rot. Airtight containers can help reduce contaminates, but won't save your CD from heat or light damage and may exacerbate humidity concerns. Try to prevent your collection from experiencing extreme swings in temperature. If you need to take a CD between two extreme environments, it is best to do so gradually. As with vinyl records, extreme swings in temperature can cause cracks or other damage to a disc' protective layers.

Leaving a disc in its packaging while it acclimates, for instance, can reduce this form of damage. If you believe your collection may be suffering, there are several steps you can take to try and recover your content. For one, seek out software to recover data from damaged CDs or companies who specialize in recovering data from corrupted discs. Creating extra copies can also help reduce risks. Of course, copyright infringement laws prevent users from creating a playable backup of their Blu-Ray collection, but saving home videos and photographs on additional storage methods is always recommended.

Furthermore, regular cleanings can help prevent dust, dirt and other environmental factors from corrupting your collection. Overall, you probably don't need to worry much about disc rot. Other forms of damage, such as scratches, are much more prevalent and dangerous to a CDs contents. However, following common sense storage strategies may reduce your exposure and help preserve your collection for the long haul.
