Scratches / Finger prints / Dust
- Pevent Scratches on both sides of discs, scratches on the 'lable side' of a disc can damage the data layer.
- Handle discs by outer edge and center hole only. Fingerprints and smudges on the disc surfaces can interfere with the laser’s ability to read the data.
- Store discs in cases/sleeves when not in use to protect them from scratches and dust.

Heat / Cold
- Optical discs should not be exposed to extreme temperatures, Heat and Cold.
- Avoid exposure of disc to direct sunlight.

Marking
- Use special disc markers or pens to write on discs, other markers or pens might damage the surface.
- Applying labels to discs is not recommended, but labels expressly designed for recordable media can be used.
Adhesive of label or barcode fails over time causing the label to become detached, a partly detached label or barcode may cause disc
to become jammed inside drive.

Cleaning
Preventative or regular cleaning is not recommended for optical media discs, as the cleaning process may create scratches on the substrate surface.
If cleaning is necessary it is advised to use a dry soft lint-free cloth. Holding the disc by the edges or by the center hole wipe the disc outward from the center hub to the outer edges of the disc. Wiping in a circular motion may create scratches parallel to the pit track and will impede error correction. 
For stubborn fingerprints and dirt wipe the disc with a soft lint free cloth moistened with water or use a cleaner specified for the cleaning of discs.
