DVDs have been the main technology used in the latest years for storing information like movies, games and music so that you may keep them in your library without using any unnecessary space on your personal computer.
All though they are very resilient these discs have their weak spots and to make sure that you do not ruin any your your discs by mistake you should know exactly what these faults are.
Heat is a prime enemy for your DVD as it can simply alter the shape of the disc and it will thus make it unreadable.
You should always avoid keeping a DVD close to a heat source or in direct sunlight.
Places like near the window or on your car's dashboard will quickly destroy a disc.
Dust is another prime candidate in the race to destroy a hard disc.
It will lay on the disc and cover the small pits that need to be read by the laser of the DVD drive.
This will simply cause it to skip and skip and skip some more when it is filled with music files or movies and if you are trying to install a game it will freeze somewhere around the middle or even better close to the end just when you are getting anxious to play the game.
Liquids - no matter the density they will mess up your disc by leaving stains and oxidised spots that will cause the disc to become unreadable.
You can solve the problem if you quickly wipe the disc with some alcohol however the best way is to avoid contact with liquids completely.
Fingerprints and sharp object are the last factors that can affect your disc the first covering the holes ans affecting the stream of data and the second will scratch the disk until the data becomes corrupted.
If all of the above are avoided then your DVD will stay in prime condition and will be in perfect shape for a long time.
