Handling Precautions
Do Not Look Into the CD/DVD Drive
Looking directly at the internal laser light source may result in damage to eyesight.
Do Not Use Discs That Are Cracked or Deformed
Because the discs rotate at high speeds, damaged discs may break apart causing injury. 
Discs that are not round and discs that have been repaired using adhesives are similarly dangerous, and so should not be used.
Drive Handling Care
Do not expose the drive to excessive smoke that may leave a residue, e.g., oil smoke, or tobacco smoke. Doing so can shorten the life of the drive lens.

When opening/closing the tray
When the computer is on, use the eject button (
page 8) or eject through Windows.
When inserting or removing a disc, be careful not to touch the lens of the drive.
Do not leave the tray open and do not touch the lens.
The lens and disc can become dusty in some conditions. It may cause malfunction in reading or writing.
Do not apply excessive force to the tray in the open position.
Never insert a foreign object such as a paper clip into the drive. Doing so may cause malfunction.
Do not place items other than discs on the tray.
Do not access the drive until after the tray is closed and the multimedia pocket device indicator 
is off.
While the drive is being accessed
Do not open the tray or move the computer while the drive is being accessed.
Doing so could cause the disc to shift position and this may damage the disc, or cause the drive to malfunction.
In addition, after running an application involving access to a disc, close the application before opening the tray or removing the disc.
