Besides putting the DVD in a protective box, it is also necessary to choose a dry and dark place to store the DVD, which is the most fundamental way to avoid the influence of light and humidity on the DVD. In addition, don't let the CD come into contact with chemical solution, so as to avoid chemical reaction and direct damage to the CD.

There is one more thing to pay special attention to. Many users may not know. In fact, it is unwise to write the logo directly on the CD with an oily pen. Although this can make the CD look more organized and easier to manage, it also brings many bad consequences. In addition to the irregular rotation of the disk mentioned above, the ink in the oil-based pen slowly penetrates into the dye layer of the disk over time, causing permanent damage to the disk, which is quite serious damage, and can be said to be "killing people invisibly". The correct way is to give up the practice of marking the CD directly with pen or paper and mark the CD box instead.

For scratches on hard objects, of course, the best way is to form a good habit, put CDs that don't need to be used immediately back into the storage box, and be careful not to touch other objects unnecessarily when using them. When there is dirt on the CD that needs to be cleaned, you should choose a soft cloth (preferably lens paper or special cloth) to wipe it radially from the inside out.
