eumig Metropolitian CCD (1977) - Rare 3 Head Model

cassette deck
Eumig from Austria was best known for it's filmprojectors, cameras and radios when suddenly in 1977 it introduced it's first compact cassette recorder. It has to be mentioned that they had introduced their proprietary cassette format recorder in 1962, but that model was exclusively made to accompany their film cameras for sincronized sound recording. Now back to this eumig Metropolitan CCD High Concert Fidelity Cassette Deck. The deck features a series of unique solutions and it was awarded with the "Österreichische Staatliche Auszeichnung" and the "Award for Design and Engineering" in Chicago. As a fundamentally new solution to the problems of synchronization, Eumig has introduced the optoelectronic synchronization control for its new cassette drives. Instead of the inertial flywheel, the control is carried out by a so-called "electronic flywheel" with a control sampling frequency of 15000 hertz. The low mass of motor and shaft (less than 2 grams) also explains the extremely short run-up time of less than 1/25 s. The two low-mass bell armature motors are also used for optimal tape winding and as opposite to freewheel control. This also makes possible to switch from one function to another without a stop button. The virtually inertia-free design of the winding motor also makes it possible to use the memory key to control a programmed tape position with great precision, both in fast forward and reverse. 

The head arrangement was also unique. Instead of the usual 3 head sandwiched-head configuration eumig used an independent playback head while the recording head was installed side by side with the erase head which also featured azimuth control with the aid of a built in test tone. The distance between the recording and playback head (sourced from Woelke - Germany) results in an audible time delay of 0.5 seconds when switching from source to tape, which can used for " echo effects " Another interesting feature was the fact that even the tape counter used a gear driven transmission instead of the more common belt drive counters of the era. A relatively small number of 10000 units were made while a slightly different version was used in the eumig Metropolitan CC (Concert Center) that featured added radio and amplifier.

eumig FL-1000 (1979) - Computer Compatible Cassette Deck

Computer Compatible Cassette Deck

This is a cassette deck introduced in 1979 by an austrian company, best known for their film camera products, eumig (Elektrizitats Und Metallwaren Industrie Gesellschaft mbH. in Wien)
Exellence both in engineering and styling combine in the Eumig FL-1000 to create a cassette deck with unexcelled performance, versatility, and elegance. The front-loading, microprocessor-controlled tape transport featureas Eumig's exclusive opto-electronic servo system and a sophisticated 3-head esign that lets you monitor directly from tape as it is recorded. Built-in test facilities permit optimizing performance for every tape type and brand, including the new metal-alloy formulations. Eumig innovation developed the opto-electronic capstan servo-control system used in the FL-1000. Traditional flywheels respond slowly and may induce rumble. The lightweight Eumig disc, with its 2500 precisely-spaced, photo-etched radii, on the other hand, produces 15,000 pulses per second as the capstan rotates. By comparin the counted pulse-rate against a fixed refernce, instantaneous speed-correction signals can be applied to the capstan within microseconds, helping lower the wow and flutter to a mere 0.035% WRMS.

The FL-1000 incorporates not only the usual 3-position "bias/equalization" switch but also a built-in Computest facility that provides individual adjustments for sensitivity and bias for cassettes of each type. When the Computest switch is engaged, normal machine inputs are bypassed, and the letter "t" appears on the digital readout. A 400Hz test tone is used to set sensitivity for proper Dolby level, and a combined 400/14,000Hz tone permits bias adjustment for a flat frequency response across the entire audio range. Both test positions use a Balance Scope, consisting of two LEDs which flash equally and alternately when the correct setting is achieved.

Unique among audio components, the Eumig FL-1000 cassette deck can be directly interfaced with almost all 8-bit computer systems (1979), such as the Commodore "Pet", Apple II, Radio Shack, etc. With the multi-machine control program, up to 16 FL-1000's can be individually controlled, simultaneously or sequentially, for any mode and any section of any tape. You can control each and every function of the FL-1000 including record, play, stop, rewind, fast forward, load counter, load memory, go to and many more. While the multi-machine control program will probably find principal use in commercial applications such as broadcast station or discotheques, even the owner of a home computer will appreciate index program facility that computer interface with FL-1000 provides. Under computer direction, the titles and locations of up to 15 selection per cassette side can be digitally recorded by the FL-1000 (subject, of course, to user change) on the first few seconds of each side of your cassette. In this way, by merely inserting a prgrammed cassette in the FL-1000 and punching a few buttons on the computer, you can read out its contents on a CRT and instruct the FL-1000 to play the selections you wish to hear in any order - with, for example, a "rewind" command at the end of your musical menu.

Alpage AL-300

The Alpage AL-300 was a cassette deck introduced in 1980 by the Alpine Electronics Inc. which is, in turn, a member of the Alps Electric Group. The Alpage AL-300 was a top-of-the-line model, one of the best 3-head cassette decks on the market. The AL-300 has a 3-head design with Closed Loop Dual Capstan drive mechanism. The AL-300 was designed for use with metal tape (and CrO2, FeCr, Normal) with independent Dolby calibration for left and right channels and also independent BIAS adjustment controls.

A slightly modified version of this deck was distributed by PHILIPS and several PHILIPS sub-brands accross the world. These versions had instead of the needle type VU meters Fluorescent Tube Peak Level meters and a large bright red LED tape counter. 

The following models were availabe: PHILIPS N5788 (black), N5781 (silver), ARISTONA SR3780, ERRES SR3788, LOEWE SR3788 and DUX SR3788.

3 HEAD cassette deck rarities

vintage audio

In this article we take a closer look to some of the rarest 3 head cassette recorders. They were either market specific models or were only made in low numbers so they hardly ever show up for sale on the second hand market.

First in this line-up is the OPTONICA RT-9100H. Optonica was a brand name used by SHARP for their high-end audio gear. This model is not necessarily rare but is definitely one of the less known 3 head recorders....with 4 head. Yes it is a genuine 3 head recorder with monitor function however there was a 4th head that recorded signals to the tape for a sophisticated music search system. It was available as OPTONICA RT-9 in Japan, OPTONICA RT-9100 the rest of the world, while the black version was OPTONICA RT-6905 that came with an additional programable timer unit.

The next model is from Austria and it was made by eumig (Elektrizitats Und Metallwaren Industrie Gesellschaft mbH. in Wien). Before eumig became known with their version of a rebadged Alpine, the eumig FL-900 or the famous eumig FL-1000 they made this 3 head model called the eumig Metropolitan CCD. Released in 1977 this cassette deck uses heads from WOELKE (Germany) mounted on a full die-cast chasis. Instead of the usual rec/playback sandwich head this model uses an independent playback head while the recording head is sandwitched together with the erase head and there is azimuth control for the recording head.

BIGGER = Better ?


These are some of the BIGGEST cassette decks ever made. Were they better than a regular sized deck ? In some cases yes, they were hiding a complex mechanical construction and sophisticated electronics to achieve the best possible sound. Let's take a look at the models and the years they were made.

The AKAI GXC-570D  was first manufactured in 1975 and it features 3 heads and 3 motors.


The eumig FL-1000 was made in Austria in 1979. This is a highly regarded cassette deck.


The OPTONICA by SHARP RT-6906 from 1981 was a 3 head machine with an extra head for a sophisticated track search system. 

The PIONEER CT-A1 from 1979 is a 3 head unit with a complex tape calibration system. Briefly sold as Linear Phase 7000 a company that was recently acuired by PIONEER.


A big and beautiful cassette deck from Norway. This is the TANDBERG TCD 3004 from 1980. 


A not so well remebered model is the TEAC A-860 from 1976.


A two box solution from Technics. This is the RS-9900US from 1977.


Here is something interesting, something you would not expect. These are two models from 1977 made by UNITRA from Poland. They are the UNITRA M-601SD and the 3 head UNITRA MDS-624. 


Finally the BIGGEST of them all but never manufactured. The LUXAN X-3K, only shown as a prototype. With this system the aim was to completely extract the tape from the cassette and run it on a free and precise tape path.
