Precision Magnetic Recording Heads.
The first sound was the sea. Then came the sounds of communication among
life forms. However, the ability to record and reproduce sound is a
development of recent history.
Teccon is proud to be acknowledged as a leader in this technology.
In reading or transmitting audio and instrumentation sound, magnetic heads
play the key role in a cast of many. They convert electrical signals from a
microphone, video camera or keyboard into magnetic impulses and record them
onto a magnetic medium. By reversing the process, a magnetic head reads the
patterns back, reconverts them into the original sounds for final
reproduction through speakers, display screens or printed copy.
The magnetic head is a precision instrument. Designing and manufacturing
them for worldwide applications is our exclusive business.
Creating industry advancements rather than keeping apace, enables us to do
more than just meet your immediate requirements. It allows us to project and
fulfil your needs for tomorrow.
Created by artists of sound technology.
When knowledgeable people with years of experience establish an environment
of sophisticated equipment, with unlimited materials and a specific
challenge, the results embody the optimum in professionalism. We are
recognized as innovators of specialized equipment, for instance, our high
density digital heads with up to 20,000fci, or the ones with 96 tracks per
half inch of tape width.
Ongoing requests from the entertainment and communications industries as
well as the OEM and end users of audio and instrumentation systems, continue
to spawn the development of unique head designs and our technology responds
with uncompromising precision.
Perfected through mechanics, optics and electronics.
The Teccon facility for precision magnetic recording heads is a harmonious
blend of design, engineering, manufacturing and quality control. We’re
staffed with people dedicated to the concept of perfection and furnished
with the latest equipment to make that possible.
Customer requirements affecting design and engineering are carefully
analyzed. Manufacturing and assembly functions are enhanced by the use of
optics and electronics, conducted in an atmosphere with control over dust,
humidity and temperature.
Each process is part of a totally coordinated operation and is supervised
with careful attention to product capability, precision performance and on
Crafted from magnetic sendust, all metal construction.
The performance and longevity requirements imposed on precision magnetic
recording heads demand that they be built from materials affording long
lasting accuracy. Years of experience confirm that our all metal heads and
choice of materials last up to ten times longer than conventional heads.
Sendust “hard-tips” are characterized by high electrical resistivity, small
grain size, low losses and less contour effect. By adding titanium, we
achieve a hardness factor far in excess of other commonly used magnetic
metals, thus an ideal material to face with the abrasive action of film and
The entire headstock is encased in solid brass with precision gap alignment
and a highly polished hard face.
The result is the Teccon hybrid head, more costly to manufacture because of
the materials, equipment, tooling and highly trained technicians, but the
reward is precision performance with a much longer wear rate.
Savings up to 300% can be realized when considered on a wear per foot of
film or tape basis, with less downtime.

Finished by hand to microscopic exactness.
Computer technology has led to many significant advances in production
procedures and efficiency. In acknowledging these accomplishments, it must
be noted that limitations do exist. We are now at the point where metal
removal is measured in microinches. Decisions concerning lapping and
polishing are based on microscopic readings and experience. The element of
human sensitivity proves to be far more accurate than any mechanical
approach to this final process, therefore, guided by the microscope, the
“finishing touch” to all Teccon heads is applied by hand.
Checked and inspected, entering and leaving each process.
The entire development of every Teccon head is governed by strict quality
control procedures. They begin with the inspection of all incoming raw
material which must meet critical standards for uniformity and
The manufacturing process itself involves over sixty individual steps, each
of which is checked for accuracy upon completion, then tested again as the
unit enters the next phase. Finally, each head undergoes a complete
Simply because we insist on excellence.
Precision performance from magnetic recording heads is our main objective
and strict adherence to this philosophy is your assurance of confidence in
every Teccon head.
Teccon and you.
We invite you to experience a personal visit to our world of precision
magnetic recording heads, where ideas become reality. Our facilities in the
foothill community of San Dimas, California offer an attractive atmosphere
for the creative technicians and skilled craftsmen who are justly proud to
serve your world of audio and instrumentation reproduction.
Teccon was founded on the philosophy that precision products demand
precision workmanship from beginning to end, that talent be supported by the
appropriate equipment regardless of cost and that client guidelines be met
with professional expertise in all respects. The daily application of this
concept manifests itself in those who rely on us for the ultimate in
magnetic recording heads. It is our business to be an integral part of your
business in the formation of ideas, solutions to problems and enhancement of
Studio and Theatre Heads
Effective November, 1986
Many years of intensive research and experience in the production of
magnetic recording heads have made TECCON ENTERPRISES LTD. pre-eminent in
this field. With modern facilities for the design and manufacture of
magnetic heads, we are able to meet any requirement or specification with
absolute compatibility of performance.
● Fifteen Times Longer Wear
● All Metal Construction
● Low Crosstalk
● Less Contour Effect
● Precision Gap Alignment
● State of the Art Technology
Sendust is a magnetic alloy originally invented by Professor Hakaru Masumoto
of the Research Institute for iron, Steel and other Metals at the Tohoku
University, Sendai, Japan. While investigating the magnetic properties of
iron-silicon and iron aluminium-alloy, he managed to achieve higher
permeability by forming the alloy Fe-Al-Si and named it Sendust (Dust from
Sendai). Sendust Alloys are characterized by fair initial permeability, high
electrical resistivity, small grain size, low losses and a hardness far in
excess of presently used magnetic materials. Most recent developments have
produced Fe-Al-Si with a still improved hardness mainly by adding Titanium
to Fe-Al-Si composition, the following properties are typical:
Bs = 8900 Gauss
uo Static = 25000
u at 1 KHz = 14000
Resistivity = 0.1 Ohms Cm
Average Grain Size: 50 um
Density = 7.0 g/cc
Hc = 0.03 Oe
Hardness = 570 Vickers
Curie Point = 410° C
Sendust provides a much lower wear rate than the permalloy materials used at
the present time, consequently, it is a more logical material to be used
with the somewhat abrasive oxide stripes on 70mm and 35mm films.
The ear is one of nature’s most sensitive devices.
Like it, the Teccon Magnetic Hybrid Head is an extremely sensitive,
precision instrument for recording and reproducing all sounds audible to the

They have precision gap alignment, clarity without excessive crosstalk and a
hardness factor beyond comparison.
And they handle multiple generations with minimal contour effect.
This all adds up to the epitome of performance and endurance.
A performance that goes beyond good sound...to the dramatic excitement of
realism. An endurance that’s equivalent to 20 times longer than you would
expect from a conventional head. For instance, longevity standards set by
Teccon Heads, based on wear per foot of film and less downtime, offer an
