DESCRIPTION
The
models
BASF
6106
and
BASF
6108
are very
compact
random
access data storage
units,
which
utilize
a 5.25" Flexy
Disk
as
storage
medium.
The
BASF
6106
stores
data
on
one
side
of the Flexy Disk,
the
BASF
6108
on
both
sides.
The
Flexy
Disk
is
rotated
at
300
RPM
yielding
a data
transfer
rate
of
125~000
bits
per second
in
single
density.
Up
to
125
kbytes of
raw
data
may
be
stored
on
a
single
recording surface in
single
density,
and
twice
as
much
in double
density.
Data
capacity
on
all
40
tracks varies
from
81.92 kbytes
(BASF
6106,
16
sec
tors
at
128
bytes)
to
368.64 kbytes, so increasing capacity
more
then four times
by
using the
BASF
6108
with
9
sectors
of
512
bytes each.
The
mini
disk drives are equipped with a
DC-
controlled
spindle drive motor, thus
no
AC-Power
is
needed.
Ceramic
read/write heads with tunnel
erase are
used
with-in
the
BASF
6106/6108
to
ensure
reliable
data recording.
The
heads are positioned with a fourphase
DC-
stepper
motor
actuator,
utilizing
a
spiral
wheel
which
provides precise location of the read/write
head
or heads
on
the
track.
Applications for both types of
mini
disk drives
comprise
word
processing
and
text
editing
systems,
program
storage for
mini
and
micro computers,
