1 Diskette
This
unit
uses
a
5.25"
mini-disk
that
records on
both
sides
as
the recording medium. Its external appearance
is
as
shown on the left.
It's
called a diskette and
is
a magnetic
sheet covered
by
a jacket.
2 Inserting a Diskette
1.
Put a finger on the
bottom
of
the
front
door
and
lightly
pull this
door
toward you
to
open it.
2.
With the label side up and the
head
window
forward,
insert a diskette
in
the slot. There
is
no other way
to
insert a diskette correctly.
3.
Push
the diskette
lightly
until
it
stops and close the
front
door.
If
the diskette
is
not
inserted all the way,
the
front
door
will
not
close. When this happens do
not
force the door closed
but
re-insert the diskette correctly.
3 Write-protection Notch
If the write-protection notch
of
the diskette
is
covered
with
a
seal
of
silver paper, etc.,
writing
of
data
is
forbidden. Reading, however,
is
possible. Some diskettes
supplied
by
Sharp
that
are called Masters
have
this part
covered
with
a
seal.
Never remove
it
because
it
prevents
trouble
from
improper operation.
Do
not
cover the notch
of
a diskette
that
is
ordinarily
used
for
read/write operations
with
a
seal,
etc. or
writing
will
be
impossible.
4 Data Read/Write
Operation
of
this
unit
is
only
by
ON/OFF
of
the power
and insertion/removal
of
a diskette.
All
reading and
writing
of
data
is
controlled by the host system MZ-80B.
For details refer
to
the software manual. A maximum
of
4
drives
can
be
operated and drives
are
designated by the
drive numbers on the
