Why Tangential Tonearm:
Why Air Cushion, Why Low Air Pressure:
The Story:
For many, many years I have really been enjoying the sound from records. My sound system is very carefully put together by fine tuning of one component with another in the desire to achieve excellent sound. And so, during my constant search for Excellency in the beginning of 2009 a wish was born to create a tangential tonearm. After a thorough study of different systems of tangential leading of tonearms I decided to use - create a tonearm that floats on a thin air cushion of low pressure. There are namely different systems of air cushion - with medium air pressure, magnetic field, by using motor drive, moving on bearing wheels…
By realizing my dream to create a tangential tonearm of my own it is tremendously important that I know how to use my skills and knowledge from engineering and that I have a vast knowledge of materials. After numerous testing of different kinds of materials and creating different versions of tonearm in the spring 2010 I finally created my product - turntable tangential tonearm ( Mili is the name I got from my little niece and can also mean
Milan Linear). This new tangential tonearm instantly replaced the old tonearm on my gramophone. By doing so, I have already started to enjoy the sound that has extremely surpassed all my expectations.
My tonearm was soon introduced to my friends and they started to encourage me to make some more examples of the tangential tonearm Mili. One day a man (who is now my friend) came to me, listened to the sound of tangential tonearm very carefully and at the end he wanted the same tangential tonearm. He told me that I have 6 month to make another tangential tonearm and if I couldn’t make another one he will come and take mine.
So I created a product that fits perfectly not only by sound but also looks good (with a little help from my daughter, an architect to be).
With help from my friends I started to test my tangential tonearm by using different cartridges, different types of turntables, different cables and audio systems… We also tested different types of compressors to see their endurance and the intensity of noise they produce. With smaller improvements I created the product which I consider good enough to offer it to the others.
Master disc, which is the basis for imprinting of the records, is made by using a cutting head in a tangential way. Therefore, the only “reading” of the sound from the records without mistakes is  the tangential way of reading from a record grove. Linearly guided tonearm does not need compensation of centripetal force - bias (antiskating), because there is no centripetal force present. On the other hand, centripetal force is present by pivoted tonearms where it starts to grow towards the centre of the record and needs to be compensated.
The flexible part of the tangential tonearm (tonearm with bearing bush) floats on a thin cushion of air in a way that there is practically no resistance between the base (lead) and the moving part of the tangential tonearm. There is also no physical contact between the moving part of the tangential tonearm and the base of the tonearm. By using a low air pressure system a compressor (which is silent) can be in the same space with tangential tonearm since it doesn’t excrete condense. By low pressure air system the amount of airflow is regulated, not the pressure.
