Handling Disks with Care
Before using disks, carefully read through the Operating Instructions, the instructions for
handling the disks, and whatever is written on the disk packaging.
If the disks are not handled properly, they may become dirty or scratched, the writing speed
may be reduced or data may not be recorded or played back properly. Other damage may
result including drive failures.
Keep the following precautions.
Do not touch the data surface.
Keep the disk surfaces clean and free from dirt, dust and fingerprints, and do not allow
them to become scratched.
Do not write on the surface of the disk with a ballpoint pen or other writing instrument nor
paste any paper to it.
Do not drop, bend, or place heavy objects on top of disks.
Do not place or store disks in locations exposed to heat, direct sunlight, humidity or dust.
If a disk is brought from a cold to a warm location, condensation may form on the disk. For
read-only disks, wipe off the condensation using a soft, dry, lint-free cloth before using the
disk. For recordable/rewritable disks, wait until the condensation dries.
When disks are not actually being used, make sure to keep them inside their protective
cases or cartridges.
If the disk becomes dirty, clean it with the followings.
