General Information about Optical Discs
Disc Loading
To insert a disc into the optical disc drive, follow these steps.
1. Press the Release button. The disc tray emerges a short way out of the drive door.
2. Gently pull the tray out until you can easily position a disc in the tray.
3. Put the disc, printed side up, into the circular impression in the tray.
4. Push the disc tray in until it clicks shut.
Note
: some discs vibrate when playing. This does not affect the optical disc drive.
Disc Care
When handling optical discs, keep the following guidelines in mind.
Hold optical discs by the outer edge and the inner hub to avoid damaging the surface. Avoid direct
contact with the disc's surface.
Avoid scratching or soiling both sides of the disc.
Do not write on or apply labels to either side of the disc. Never write with a ballpoint on the surface of
the disc.
z
Do not use stickers, labels or write on both sides of a disc. Unless you use specific
label kits, never use a tape or sticky material to label optical discs. Since the data layer
of a disk is right beneath the printed label, writing with a pen can scratch the thin
reflective aluminium coating. Use soft-tip pens especially for re-writable disks that are
even more sensitive.
z
Do not scratch or polish the label side. The pits and lands (microscopic holes and flat
areas) that encode the information in the CD are on the label side, and not on the
surface read by the lens. Large scratches on the underside, however, can often be
repaired using special polishing kits. Most of the time, the laser, which focuses on a
layer within the clear base, is able to see past small scratches, in much the same way
the human eye can focus on objects outside when looking through a window.
Keep the disc away from direct sunlight, high temperatures, and humidity.
z
Keep optical discs away from high temperatures. Don't subject disks at temperature
levels exceeding 37
°
C. Exposure to direct sunlight over long periods easily warps a
disk. Low temperatures are not a hazard, but wait for a stable temperature before
loading a disk. Disks burned using CD-writer drives are more sensitive and should be
stored at room temperature whenever possible.
z
Moisture does not affect other types of discs, but avoid exposing re-writable disks to
liquids. In case of accidental spills on discs, rinse it off with lukewarm water and wipe
dry with a soft cloth. Be careful with sticky or oily substances that trap dirt and dust.
Proper cleaning is important to achieve optimal performance. Using a soft, slightly damp cloth, wipe
the disc from inside the disk and rub outwards. Do not wipe in circles but clean in the same outward
direction. Wiping the label side in circles can scratch a section of the data track. Slightly dipping the
cloth in warm water is enough. Using cleaners and solvents can do damage.
Caution
: since discs are coated with thin layers of aluminium and plastic, avoid using benzene, paint
thinner, record cleaner, static repellent, or any other chemical to clean the disc. Chemicals and cleaners can
damage the disc.
