Handling Your Diskettes
Be careful with your diskettes. Because each piece of information occupies such a small
area on the diskette, small scratches, dust, food, or tobacco particles can make the
information unusable. Be sure to remember the following:
•
Do not touch the recording surfaces.
•
Keep diskettes away from magnets and magnetic field sources such as telephones,
dictation equipment, and electronic calculators.
•
Keep diskettes away from extreme heat and cold. The recommended temperature range
is 10 to 60
°
C (50 to 140
°
F).
•
Proper care helps prevent loss of data.
•
Make backup copies of your diskettes regularly.
