1. Laser lens
When the disc tray is fully opened, the edge of the computer will extend
slightly over the disc tray. Therefore, you will need to turn the disc at an
angle when you place it in the disc tray. After seating the disc, however,
make sure it lies flat.
■
Do not touch the laser lens or any portion of its surrounding casing as
this could cause misalignment.
■
Prevent foreign objects from entering the drive. Check the surface of
the disc tray, especially the area behind the front edge of the disc tray,
to make sure there are no such objects before closing the drive.
4. Press gently at the center of the disc until you feel it click into place. The
disc should lie below the top of the spindle, flush with the spindle base.
5. Push the center of the disc tray to close it. Press gently until it locks into
place.
If the disc is not seated properly when the disc tray is closed, the disc
might be damaged. Also, the disc tray might not open fully when you press
the eject button.
