CARE AND HANDLING OF CD-ROM DISCS
The following guidelines represent the current thinking for the care
and handling of CD-ROM discs, by a number of CD-ROM disc and drive
manufacturers. The validity and usefulness of most of these
guidelines have not been substantiated by Government testing and
therefore are presented for information only.
Wash your hands before contact with the disc. If available, wear
lint-free cloth gloves, finger cots, or talc-free latex gloves.
If you must wipe the disc, do so with a soft, dry, lint-free cloth in
a radial motion- that is from the inner to the outer hub- not in a
circular motion around the disc like you might do for a phonograph
record. The most devastating scratches are those which occur along a
radius of the disc which can obscure a long stream of pits.
Certain cleaning agents and solvents can damage the discs. Some of
these include: gasoline, paint thinners, benzine, acetone, carbon
tetrachloride, chlorinated cleaning solvents, ammonia, and household
detergents which contain ammonia. Do not clean with a water soaked
cloth. The use of Isopropyl alcohol, the ingredient in many
commercial CD cleaning products, as well as certain waxes and acrylic
liquids, is still questionable.
Do not clean the label side of the disc.
Use of a CD-ROM caddy is highly recommended during transport and
operation. Limit the amount of physical contact with the disc.
Always handle the disc by the outer edge and/or the inner (hole) edge.
Never touch the data surface.
Discs like to "live" in the same conditions that people do; that is:
They don't like to be manhandled
They don't like exposure to temperature extremes
They don't like exposure to excess humidity
They don't like exposure to high intensity UV light
