In order to preserve information, laser disks need to be protected from what?

To begin with, let’s figure out what exactly is a laser disk?

A laser disc is a disc with a silvery surface that stores information read by the laser. The surface of the disc is covered with circular tracks made up of tiny depressions containing information.

And therefore, it is extremely important to protect yourself from damage to the disk and subsequent loss of information. To do this, protect the disc from excessive light, shock, scratches, dirt, heat, cold and keep it out of the hands of children.
