Use
the following procedure
for
cleaning each head.
(1)
Remove a cleaning Q-tip from its container, without touching the cotton swab.
(2)
Saturate the Q-tip cotton swab with
91
% isopropyl alcohol.
NOTE
Do
not
dip the swab into the isopropyl alcohol,
but
pour
the
liquid
over the swab
so
as
not
to
contaminate the
alcohol.
CAUTION
DO
NOT
TOUCH THE
FACE
OF
THE
MAGNETIC
HEADS
WITH YOUR FINGERS.
ACIDS
EMITTED
FROM
THE
SKIN
CAN
CAUSE
PERMANENT
DAMAGE
TO
THE HEAD. DO
NOT
BLOW
ON
THE HEADS
AS
MOISTURE WILL
CONTAMINA
TE
THE HEADS.
(3)
Carefully clean the slider surface and edges
of
the head.
NOTE
To
facilitate cleaning the heads, the positioner may be
moved forward from its
fully
retracted position about
1/2
to
3/4-inch.
This will cause the head pairs to separate more
thus allowing more space between the heads.
(4)
Clean the two bleed holes in the
head
by
rotating the cotton swab at each hole
opening (this
will clear any loose oxide
or
contamination that may be trapped at
the edge of the holes) - make sure you do this from the slider face side
of
the
head - not from the back.
(5)
Wipe the slider face dry using a second cotton swab; this operation must
be
done
before the alcohol has evaporated.
(6)
Inspect each head after all heads
have
been
cleaned. Repeat the cleaning process
if necessary.
6.4.2
INSPECTING AND CLEANING THE FIXED DISK
Remove the cover from the disk drive and raise the Logic PCBA to the extended position.
Instructions for removal
of
the disk drive cover
are
contained
in
Paragraph 2.2. Also
remove the disk cartridge, if necessary.
Use
a dental mirror
and
a suitable light source (such
as
a penlight) to inspect each disk
surface before and after cleaning.
It is important that all debris
be
removed from the disk
surface.
Use
the following procedure
for
cleaning each disk surface
..
(1)
For front load models only, gain access to the lower fixed disk(s) by removing the
access cover plate
on
the side of the lower disk cover.
(2)
Prepare two cleaning wands
as
follows.
•
Insert a lint-free pad* into the barbed slot of wand.
• It is important to rotate the wand counterclockwise, thereby wrapping the
pad
completely around the wand.
Take
care not to contaminate the pad.
*Some pads, such
as
Texpads (from the Texwipe Co., Hillsdale,
NJ
07642)
come packaged
in a sealed container already saturated with
90% isopropyl alcohol.
