A GUIDE TO BRITISH TAPE-RECORDERS
'A Guide to British tape-recorders' is a fully
illustrated, major work which traces the history and development of
sound-recording, especially of the magnetic tape-recorder from the
pioneering work by Valdemar Poulsen and his wire recorder, through
the development of plastic based tape, to simple domestic-user
models and the complex scientific, instrumentation and
communication recorders of recent years. It also looks at the
development of the associated tape, head and ancilliary components,
recording the potted histories of the 100+ British tape-recorder
and component makers, and their models.
It is hoped this work will encourage others to fully research their
chosen companies before it is too late, just as I have for Brenell,
Truvox, Thermionic Products, Racal... and have George West and
Terry Martini on Ferrograph. Be warned, time is fast running
out!
In the beginning
At the turn of the 20th century, the Danish telephone engineer,
Valdemar Poulsen, pioneered the recording and retention of sound by
electro-magnetic impulses onto wire. And so began the battle
between Edison's direct recording onto waxed cylinders and
gramophone discs, and Poulsen's onto steel wire or steel-ribbon;
Poulsen had also prophesied magnetic oxide coated cards and paper
media. But it was not until BASF in Germany had mastered the
magnetic oxide coating of plastic tape in the 1930s, did
tape-recording, as we know it, come to the fore. Meanwhile in
Britain and America, much effort was being put into perfecting
steel-wire or steel-ribbon recorders the more so as Semi Joseph
Begun, a German pioneer of steel-ribbon recording had escaped Nazi
Germany and joined Brush in the USA. The Allied Forces relied
heavily on wire recorders during the war - American designs were
license built in Britain by Boosey & Hawkes - but although the
new plastic or paper based magnetic tape technology was no secret
in the late 1930s, it took the clarity of supposedly 'live'
broadcasts by the Nazi propaganda machine to awaken the allies to
the very real advances made in Germany by BASF and AEG in magnetic
tape-recording.
Led by M J Pulling of the BBC and E M Payne of EMI, an immediate
post-war analysis of these pioneering German AEG 'Magnetophons' was
undertaken for the British government in late-1945, opening the
door to the development of magnetic tape-recorders in Britain by
EMI for broadcasting and record production, by Scophony and Plessey
for scientific use, and by GEC and RGD for 'domestic' use but it
was not until 1948 that Thermionic Products began license building
the first commercially viable domestic/business recorders - the
Recordon dictating disc-recorder and the Brush Soundmirror, both
developed by Semi Joseph Begun - that magnetic tape-recording
became a commercial reality.
In 1948 there were only three British companies active in the
tape-recorder market: Scophony, EMI and Thermionic Products. Then
in 1949 Wright and Weaire (Ferrograph) entered the market and by
1950 there were some 17 companies offering everything from basic
home-assembly kits to high quality professional recorders, many for
cine-photography. By 1955 there were some 30 companies: tape had
arrived and live studio recordings were now being mastered onto
tape for reproduction onto disc. The days of direct disc-recording
and optical recording to film had come to an end, forcing MSS (a
leader in disc-recording) to turn to the manufacture of magnetic
tape and professional tape-recorders.
When in 1955 Collaro, a famous gramophone maker, launched their
brand new tape deck, it encouraged the major domestic audio
companies to enter the market. Then in 1959 BSR (Collaro's major
competitor) launched their budget (and bomb-proof!) Monardeck
causing a peak in 1960 with over 70 British tape-recorder brands,
whose demand was boosted by the introduction of the affordable,
1/4-track heads, reducing the relative cost of tape but, above all,
allowing the novelty of synchronised cine-film soundtracks and,
with an auxiliary amplifier, stereophonic hi-fi to the masses
through high quality pre-recorded tape-records from EMI, Columbia
and others.
The makers
The burning question, "Which was the first British tape-recorder?"
is not a simple one to answer. If we ignore the pre-war
Blattnerphone and Marconi-Stille steel-ribbon recorders, the first
British plastic-tape-recorder was announced in April 1947 by
Plessey for scientific use: but little is known of this 4"
portable.
In 1947, EMI had developed their BTR1 studio recorder based on the
German AEG Magnetophon, then in 1948 Thermionic Products launched
their British-built 9" magnetic oxide coated disc recorder, the
'Recordon' for dictation, followed by the new paper-tape
'Soundmirror', but both were licensed from Brush in the USA.
Officially launched at the May 1949 Olympia show, the Soundmirror
truly was the first British-built, complete tape-recorder, for
although Wright & Weaire had demonstrated their prototype deck
in October 1948, their first complete tape-recorder, the
'Ferrograph', did not come on stream until late 1949 by when RGD
had also entered the market as had General Laminations with their
'Sound Magnet', using an unidentified tape deck, along with several
others including Baird.
Meanwhile, in 1948 Scophony had been quietly developing a tape deck
for the British government. Their first commercial model was
launched in July 1949 as the Scophony-Baird 'Cine-Soundmaster'
especially to synchronise sound to silent movies. This was followed
in 1951 by their Scophony-Baird 'Soundmaster' domestic
tape-recorder which offered the first direct competition to the
Soundmirror.
By 1950 several new decks began to appear from the simplest and,
frankly, quiet crudely designed kit-built decks, to complete and
quite advanced models for quite diverse markets. At the bottom of
the market were those aimed at radio enthusiasts who happily built
kits to plan using parts supplied by High Street radio/electronic
component dealers such as Stern, MOS, Premier and Garland - such
dealers soon began offering complete tape-recorders using the new
Lane deck, soon joined by the new Motek. Commercial and business
users were offered various tape-recorders for dictation or
answerphone/automatic dialers, while the professional user was
offered models by Bradmatic, EMI and Leevers-Rich.
In 1951 came a new legal requirement for airfield to pilot
communication recorders, a field soon dominated by Thermionic
Products in the development of multi-track voice recorders. From
this came airborne magnetic-tape based Flight Data Recorders for
all commercial airliners and most military aircraft.
While the amateur market was well catered for, the domestic-user
market remained quiet. This was understandable for Britain was
still subject to rationing and tape was very expensive: besides,
few saw any reason to replace their expensive gramophone
collection. Most entertainment was after all found at local cinemas
or dance halls; few sat at home listening to the radio or
gramophone to pass the time away except after Sunday lunch and "Mrs
Dale's diary".
However in 1953, Max Grundig launched his well built and specified
German-made tape-recorders in Britain. These were aimed at the
amateur cine-photographer to add sound to their films. The
domestic-user market, now freed from rationing and buoyant with the
Queen's Coronation with demand for the new fangled television, saw
the audio entertainment market take off and by 1954, famous names
such as Ferrograph, Truvox and Brenell began dominating the quality
domestic and semi-professional tape-recorder markets, albeit
trailing well behind Grundig in sales!
The British domestic-user market rapidly expanded following
Collaro's new Transcriptor tape-deck of 1955, which allowed radio
manufacturers to enter the market for the first time with an
affordable proprietary deck - even if only to maintain their market
share - but their excellent Transcriptor was replaced by the,
arguably inferior, Studio in 1957 which soon faced stiff competitor
from fellow turntable makers, Garrard (with their easy to load
cartridge deck) and BSR's inexpensive but remarkably robust
Monardeck TD1 which led to a flood of new budget, badge-engineered
tape-recorders entering the market, many contract built by Plessey
for the home-catalogue market.
The early-mid 1960s were the hay-day of British tape-recording with
a bewildering range of models - and enthusiasts' magazines - but it
was short lived for following the introduction by Philips of their
incredibly versatile, easy to load 'Compact Cassette' in 1963 -
which for the first time truly allowed music (albeit lo-fi) on the
move - it soon decimated the global open-reel market and, along
with more open trade with Japan, had by the end of the decade,
destroyed the domestic open-reel market, along with much of the
British tape-recorder industry.
While Garrard's easy to load 1/4" tape cartridge offered high
fidelity, Philips 'Compact Cassette' offered an abominable
low-fidelity but through wise marketing they now offered
pre-recorded albums as 'Musicassettes' which could be played on a
portable radio-cassette or in the car, even if the speed varied
with the car's and the cassette player had consumed the tape before
journey's end! But by the late 1960s, advances in technology,
especially of tape formulations had brought acceptable hi-fi
standards to the masses, sounding the death knell of the cumbersome
and bulky open-reel tape-recorder. The utterly reliable Japanese
models had rightly forced many substandard British brands off the
market, indeed, by 1970 there were barely 30 British open-reel
tape-recorder brands left - only a handful in the domestic-user
market led by the Thorn group (with their superior high grade
tape-deck), Truvox, Brenell and Ferrograph. Within five years their
numbers had been reduced to barely 10, over half of which were now
specialists in commercial voice logging, studio, instrumentation
recording and air-borne Flight Data Recorders. Those few which
survived, such as Brenell, Ferrograph and Leevers-Rich now
concentrated on the professional, scientific and studio markets,
only to fold with the universal adoption of digital recording in
the 1980s.
Many of the 100+ British companies lasted barely 2 years - the
average was 9-1/2 years; few lasted more than 20 years. Thermionic
Products survived the longest, some 45 years, ending their time as
Racal-Thermionic, later Racal Recorders, making multi-track voice
loggers and instrumentation recorders: they even acquired the Zonal
tape business and were the last to produce there own heads. They
were the last in the business.
Tape decks
The term 'Tape Deck' was actually registered by Wright &
Weaire, forcing others to use terms such as 'tape-panel' to
describe the transport mechanism, until Truvox challenged the right
to the now generic term, whereupon it passed into common
usage.
In essence, a tape deck comprises a flat, rigid plate onto which
were screwed heads, motors and control gear. The deck was
invariably a 1/16" to 1/8" thick steel or aluminium alloy plate,
but Bradmatic used a 3/4" thick Tufnol phenolic-resin board, while
Truvox used a 3/4" furniture-grade plywood deck. These were
perfectly stable for 1/4" tape in domestic use, but wider tapes,
especially 1" for the demanding professional and industrial
applications, caused considerable drag on the guides and heads
which along with their sheer weight, caused flimsy decks to flex
and track alignment to go awry. This was soon resolved by thicker
cast-alloy sheets or fully webbed cast-alloy decks.
Motors were at first fractional-horse power jobs from gramophones
(Garrard and Collaro) or small fans (BT-H/AEI). Most early decks
used for simplicity three motors, often of single speed, but many
opted for two speeds by manually swapping belt positions on
pulleys, or using capstan sleeves for extra speeds. By the late
1960s professional decks were using superior hysteresis synchronous
capstan motors from AEI in Britain or, more usually, Papst of
Germany. Studio models, with their heavy 1" tapes required more
powerful motors and turned to direct drive capstan motors, some
two-speed, but by the 1980s, studio models were increasingly using
powerful computer controlled, twin capstan drive to handle the now
standard 24-track, 2" tapes.
Heads
Apart from the very few head makers such as Bradmatic, most heads
were assembled in a quiet corner of the tape deck maker's factory,
using fly-pressed laminations, wound on a basic lathe or treadle.
But soon, companies such as Wright and Weaire, Brenell and Truvox
were offering their own full and half-track mono heads to others.
Then independent head makers such as Marriott began to corner the
domestic-user market - they produced for BSR - while engineers who
had worked with Marriotts, now specialised in studio and
multi-track heads such as Branch & Appleby and, later, Phi
Magnetronics.
The arrival of 1/4 track was first met in Britain by the German
'Miniflux' head but by the early 1960s the Germany 'Bogen' head
became dominant in the high-end domestic and professional
markets.
Tape
Most early magnetic tape sold in Britain came from Scotch (3M of
the USA) - after all they had pioneered tape production in America;
this was widely branded or licensed to others, such as to Wright
& Weaire and Pyral of France. Early tapes were robust
paper-backed or fragile acetate based, but BASF used a superior PVC
while the Americans turned to polyester.
The major British tape maker was EMI, closely followed by MSS, with
their 'Mastertape', and Zonal (who began in the film industry -
they later became Ilford-Zonal). Yet the pioneers of magnetic tape
(BASF and their IG Farben sister, Agfa) were relative late comers
to the British market mainly through trade restrictions. By then
the Scotch formula has been adopted as standard by the American NAB
and the BBC: ironically BASF now standardised on the 'Scotch'
formula with their 'LGS' tape but clever marketing tactics soon saw
BASF ousting EMItape as principal suppliers to British tape deck
makers, reaping repeat sales. Excellent as their LGS tape was,
their new LP35LH low noise/high fidelity tape of 1970 (formulated
for cassettes) set new standards in audio performance and rapidly
led to the demise of Britain's EMItape, Mastertape and Zonal who
now turned to the professional recording market.
With the move to digital hard disc recording, demand for new tape
was now so low that the industry collapsed in the late 1990s;
limited production resumed for the military and space programmes
and in 2004, RMG restarted production of the former BASF/Agfa/Emtec
formulations in professional matt-backed and glossy-backed
'classic' tapes. Computer data storage on tape is also proving far
more stable in long term storage than solid state media, so tape's
future is looking more secure! So buy new tape, or lose it for
ever!
Just as vinyl is making a rapid recovery, so too is analogue audio
recording, valve amplifiers - even cassettes are enjoying a revival
- so, hopefully, will open reel decks... one day.
