7.4 Handling CD-ROMs
Since no physical contact with the CD is involved in reading CD-ROMs, they
have a virtually unlimited lifetime. You must nevertheless observe a few points
with regard to care.
Care of CD-ROMs
When you remove a CD-ROM from its package, you should observe the
following rules:
● If the CD-ROM is dirty, you can clean the surface carefully with a soft, dry,
clean cloth. Never use a damp cloth and never use cleaning agents or
solvents. Vapor near the CD-ROM (such as ammonia) can cause damage.
Most HiFi suppliers sell special cleaning cloths for CDs.
● CD-ROMs can be damaged by direct sunlight or excessive heat (> 55 °C).
You should therefore never try to remove dirt using a hairdryer or similar. The
maximum rate of temperature increase per hour is 15 °C.
● As with floppy disks, you must not bend or scratch the surface of a CD-ROM.
Avoid shocks.
Always keep CD-ROMS in their original packaging if not used.
