Why should CDs and DVDs be kept in a cool place?

The invention of CDs and DVDs revolutionized the way we store and access information. With their high storage capacity, easy portability, and durability, CDs, and DVDs quickly became the preferred medium for storing data, music, movies, and more. However, despite their many advantages, these optical discs are also susceptible to damage, particularly from heat. Let’s  explore why CDs and DVDs should be kept in a cool place and how temperature affects their longevity.

Why CDs and DVDs Should Be Kept in a Cool Place?

CDs and DVDs are made up of multiple layers of materials, including polycarbonate, aluminum, and dye. These layers are very sensitive to changes in temperature, especially high temperatures. When exposed to heat, the materials can warp, crack, or delaminate, causing the disc to become unreadable or unplayable.

Temperature is not the only factor that affects the longevity of CDs and DVDs, but it is one of the most significant. Other factors that can damage these discs include exposure to light, humidity, and dust. However, temperature is the easiest factor to control, making it the most important.

How Temperature Affects CDs and DVDs?

The ideal temperature range for storing CDs and DVDs is between 41°F and 68°F (5°C and 20°C). Anything above or below this range can cause damage to the discs. At high temperatures, the materials in the discs can expand and contract, leading to warping or cracking. At low temperatures, the materials can become brittle and prone to cracking if they are not protected by CD/DVD cases. You can find one of the finest CD cases at NeoOnline.

In addition to the direct damage that temperature can cause to the discs, it can also affect the adhesive used to attach the layers of the disc together. High temperatures can cause the adhesive to break down, leading to delamination of the layers.

How to Store CDs and DVDs Properly?

To ensure the longevity of your CDs and DVDs, it is essential to store them in a cool place. Here are some tips for storing your optical discs properly:


  • Use high-quality CD/DVD cases to protect the discs from dust and scratches.
  • Store CDs and DVDs in a cool, dry, and dark place, away from direct sunlight or heat sources such as radiators, heaters, or direct sunlight.
  • Avoid storing discs in places with high humidity or moisture, such as basements or bathrooms.
  • Store discs vertically, rather than horizontally, to prevent warping.
  • Handle the discs by the edges, and avoid touching the disc’s surface.


CDs and DVDs are excellent mediums for storing information, but they require proper care to ensure their longevity. The storage space of a CD might not seem like a lot in today’s world of terabyte hard drives and cloud storage, but it was a significant step up from the storage capacity of cassette tapes and vinyl records. Keeping them in a cool place is essential, as high temperatures can cause irreparable damage to the discs. By following the tips outlined above, you can protect your CDs and DVDs from damage and ensure that they remain playable for years to come.
