DISK DRIVE
the disk drive. Using non-ACT disks, not manufactured to
the same high standard,
may
result in intermittent read and
write errors, rendering information stored on the disk
totally unintelligible.
The
Sony OA-D31 V
disk
drive uses 3.5
inch
70
track
single-sided MicroFloppy disks.
The
disks are encased
in
a
rigid plastic shell
and
feature
an
automatic
shutter
and
a
metal
centering hub.
Two
versions of MicroFloppy disks exist,
which
are directly
compatible
and
interchangeable,
the
only
differences being
in
minor
mechanical
details.
The
auto
shutter
of
the
earlier
versions of
the
disks
can
be
latched
open, exposing a portion
of
the
disk
surface.
The
latch
is released by squeezing
the
corner of
the
disk,
marked
by
the
arrow labelled
"PINCH".
On
later
versions of
the
disk,
the
shutter
cannot
be
latched
open.
The
shutter
protects
the
disk
media
from
contamination
by dust,
dirt
or
fingerprints, allowing
the
disk
to
be easily
handled
without
affecting
the
integrity
of
stored
data. When
inserted
into
the
drive,
the
shutter
automatically
slides
open, allowing
the
read/write
head
of
the
drive access to
the
recording media. Removal from
the
drive
automatically
closes
the
shutter.
The
metal
centering
hub
ensures
that
the
disk is
accurately
positioned
on
the
disk
drive
motor
spindle.
