How does one properly store optical discs for prolong usage?
There are many factors that affects the prolong usage of an optical disc. The following are some information on the conditions of storage for optical disc.
* Reduce exposure of light (sunlight)
The exposure of sunlight causes heat build-up in the discs’ recording layer thus degrading the disc recording quality.
* Minimize prolong periods in moisture conditions
The polycarbonate of the optical disc is vulnerable to prolong exposure in moisture conditions caused from spills, humid air, or immersion. The water may be absorbed into the disc and have an affect on the recording materials. Returning the discs to dry environment will dissipate the moisture absorbed in the disc. Warning: Water may leave behind contaminants within the discs
* Avoid strong organic solvents
It is highly recommended that all optical discs be not exposed to strong organic solvents such as acetone and benzene since these materials can dissolve polycarbonate. While limited exposure to mild solvents, like isopropyl alcohol and methanol, are acceptable for cleaning purposes due to the high evaporation of the solvent and the inability to dissolve polycarbonate.
* Effects of magnets, X-rays, and microwaves
1. Magnets should have no effects on optical discs
2. X-rays will not harm the optical discs (Airport detectors)
3. Microwaves should be avoided – it will destroy both the disc and microwave oven
* Storage of the optical disc
It is best to storage an optical disc in a case – preferably a slim case, a jewel case, a amaray case, a snapper case, etc. – the case protects the optical disc from any airborne contaminants and protects the discs from any rapid environmental changes causing stress upon the disc. For long storage, it is recommended to label the case and not the optical disc since labels may absorb moisture over a long period of time.
