The CDs can hold about 700MB (same as a folder full of photos), while the DVDs hold up to 4.7GB (as much as it takes for a full-length film). But how long they will "live" depends on many things we can control.
Manufacturers say they can last anywhere from 5 to 100 years - a huge difference! The truth is that the actual lifespan depends mostly on how we take care of them.
The main "enemies" of discs are humidity, high temperatures (such as inside a car in the summer), and direct sunlight. Also, cheap CDs and DVDs usually do not last as long as higher-quality ones.
Fortunately, there are simple ways to protect our discs and make them last as long as possible. Here are some practical tips that anyone can do:
- Proper storage: Put them in a cool, dry place, away from windows and radiators. A cupboard or drawer is ideal.
- Beware of scratches: Always hold them by the edges, like you would hold a vinyl record. Never touch the shiny side where the data is.
- Proper cleaning: If cleaning is necessary, use a soft cloth and wipe from the center outwards (not in circles). A little rubbing alcohol helps for stubborn stains.
- Away from chemicals: Avoid cleaning sprays, solvents and other chemicals that may damage the surface.
- Using correct cases: The plastic cases that come with the discs protect them from dust and bumps. Don't leave them outside without protection.
- Do not touch the recording surface: The bright side is where your data "lives." Even a fingerprint can cause problems.
- Create copies: Copy important files to other drives or to your computer. That way if one fails, you'll have a backup.
- Storage when not in use: If you are not going to use them for a long time, put them in a box or cupboard away from light and moisture.
- Sun protection: The sun is enemy number one. Never leave them in direct sunlight, such as on a desk next to a window.
- Avoiding high temperatures: Do not leave them in the car in the summer, near radiators or other heat sources that may "melt" them.
- Check the humidity: Bathrooms, kitchens, and basements often have high humidity. These places are not suitable for storing discs.
- Surface repair: If a disc is not being read properly, there are special products in stores that can "polish" minor scratches and restore it.
Conclusion: With a little care and attention, our CDs and DVDs can last for many years. Attention to detail really makes a difference!
💡 For those who don't know: Nowadays, there are more reliable storage options, such as external hard drives, USB sticks, and cloud services (like Google Drive). It's worth considering moving your important files there.
