Handling and Storing Diskettes
Inside the protective diskette case is a flexible disk with a
magnetic-sensitive coating. This disk can be damaged by
heat, dust, a magnetic field, or even a fingerprint. Use
the following guidelines when handling and storing
diskettes:
Ÿ
Data is stored on the magnetic surface of the diskette.
On 3.5-inch diskettes, this surface is protected by a
plastic cover. If the cover is damaged, do not use the
diskette, because it could cause permanent damage to
the diskette drive.
Ÿ
A protective slide on the top of a 3.5-inch diskette
covers part of the magnetic surface. The diskette
drive moves this slide to read data from or write data
to the diskette. Do not move this slide, because
fingerprints and dust can cause loss of data.
Ÿ
Keep 5.25-inch diskettes in their covers when you are
not using them. The covers protect the exposed
surfaces on the diskettes.
Ÿ
Never touch the disk itself.
Ÿ
Keep diskettes away from magnets or devices that
create a strong magnetic field, such as electric motors
and generators. Diskettes are sensitive to magnets
found in television sets, stereo speakers, and other
such items. A magnetic field can erase the data on
your diskettes. Do not set diskettes on the monitor or
use magnets to attach notes to your personal
computer.
Ÿ
Do not store diskettes in high temperatures, low
temperatures, or direct sunlight. Temperatures
ranging from 10° C to 52° C (50° F to 125° F) are
acceptable for 5.25-inch diskettes, and 4° C to 53° C
(39° F to 127° F) are acceptable for 3.5-inch diskettes.
Keep diskettes away from heat. The plastic outer
covering might warp, damaging the diskette.
