MODEL

DISK
SYSTEM
•
Handle
diskettes
by
the
jacket
only.
Do
not touch any of
the
exposed
surfaces.
Don't
try to
wipe or clean
the diskette surface;
it
scratches
easily.
•
Keep
diskettes
out of
direct sunlight
and
away from
heat.
•
Avoid
contamination of
diskettes
with
cigarette ashes, dust or other
particles.
•
Do
not write
directly
on
the diskette jacket
with
a
hard
point
device such
as a
ball
point
pen
or lead pencil; use a
felt
tip
pen
only.
•
Store diskettes
in
a vertical
file
folder
on
a shelf
where
they
are
protected
from
pressure
to their
sides
(just as
phono
records
are stored).
• In
very dusty environments, you
may
need
to
provide
filtered air to the
computer room.
Tips
on Labeling
Diskettes
Each
diskette
has
a
permanent
label
on
its
jacket.
This
label
is
for "vital
statistics" that will
never change. For example,
to
help keep
track of diskettes,
it's
a
good
idea
to
assign
a
unique
number
to
each
diskette.
Write such
a
number
on
the
permanent
label.
You might
also put your
name
on
the diskette,
and
record
the date
when
the diskette
was
first
put into use.
Remember,
use only
a
felt tip
pen
for
marking.
This
fc
'permanent
1
' label
is
not
a
good
place
to
record the contents of the diskette
since
that will
change, and you
don't
want
to
be erasing or scratching out
information
from
this label.
