APPENDIX
F.
Diskette Description, Handling, and Format
The flexible disk,
or diskette,
is permanently
enclosed
by
a
durablel
plastic covering.
This outside
Jacket allows
the diskette to be handled and
at
the
same
time
gives
a
certain
degree
of
protection ror the oxide surface within.
The covering also provides rigidity to the diskette, allowing
it
to
be easily inserted into and removed from the diskette
d,.. i
ves.
To extend the usable life of a diskette and to
maximize
trouble-free
operationl
the diskette should be handled with
reasonable care.
The
following
points
of
diskette
care
should
be
followed.
Most manufacturers usually list these
points on the
protective
envelope
of
the
diskette
as
a
reminder.
1.
The diskette should be returned to its protective
envelope when not in a drive unit.
2.
The
diskette
in its
envelope
should
be 'stored
vertically.
It
should not be stacked or placed
under heavy
pre~sur~
as this can cause warping of
the oxide surface.
3.
Too
many diskettes should not be forced into one
box.
4.
The
diskette
should
not
be
exposed
to
any
magnetizing
force
in excess of
50
oersted.
The
50
oersted
level
can
be
reached
about
three
inches
away
from
a
typical
source
such
as
electric motors,
trans rormers,
etc.
5.
Diskettes should not be subjected to extremes
of
heat.
They
should
not
be
kept
in
direct
sunl
i
9 h
t.
Warp i ng can resu
1
t.
6.
The label on the diskette should only be
USTitten
on
with
a
~elt-tipped
pen.
Pencils, ballpoint
pens,
or extreme pressure from
felt-tipped
pens
can emboss the oxide surface within.
7.
The
physical
oxide
surface
should
never
be
touched.
Skin oils transferred to the
su~face
in
this
manne~
can attract
and
retain dust and other
c ontami nants.
