When the disc tray is fully opened, the edge of the computer will extend 
slightly over the CD/DVD/BD tray. Therefore, you will need to turn the 
CD/DVD/BD at an angle when you place it in the disc tray. After seating the 
CD/DVD/BD, 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.
