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
"permanent"
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.

properly connected and
turned on?
