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

4o

tracks varies

from

81.92 kbytes

(BASF

6106,

16

sectors

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.

"intelligent"

desktop calculators

and

the

hobby

micro

computer

market.
