11.3 CD-ROM
Unlike a floppy disk or a tape cartridge, a CD-ROM cannot be written to (ROM =
read-only memory).
● If a CD-ROM gets dirty, you can clean its surface, very carefully, with a soft,
clean and dry cloth. Never use a damp cloth or any cleaning agents or solvents.
Vapors such as ammonia in the immediate environment may cause damage.
In most hi-fi shops you can buy special cleaning cloths for music CDs, and you
can safely use these to clean CD-ROMs.
● CD-ROMs are sensitive to direct sunlight and to heat in excess of 55°C. Never
try to blow dust away with a hair-dryer. The maximum allowable rise in temper-
ature per hour is 15°C.
● Like floppy disks, CD-ROMs must not be bent, and you must not scratch their
surface. Dropping CD-ROMs may also damage them.
