Around the World In 80 Lathes, Part 19

Around the World In 80 Lathes, Part 19

Those among our readers with an interest in photography will certainly be familiar with Rollei, a company that started in 1920 in Braunschweig, Germany, manufacturing optics and photographic equipment. Even earlier, in 1869, Ernst Leitz founded Ernst Leitz Wetzlar, in Wetzlar, Germany, manufacturing optical instruments, microscopes and Leica rangefinder cameras. Even prior to that, Fritz Wiktor Hasselblad started Hasselblad in 1841, in Gothenburg, Sweden. Just a few years later, Carl Zeiss launched his own company in 1846 in Jena, Germany. George Eastman founded the Eastman Kodak Company in 1888, in Rochester, New York. Sherman Fairchild started the Fairchild Aerial Camera Corporation in 1920 (the same year that Rollei was founded in Germany) and the Fairchild Camera and Instrument Corporation in 1927, in Delaware.

Interestingly, it was the Fairchild Aerial Camera Corporation of New York that started manufacturing disk recording lathes in the early 1930s, an example of which was covered in Issue 164, a direction which was to be continued by the Fairchild Recording Equipment Corporation, founded in 1931 in Whitestone, New York. The result was a range of disk recording lathes, cutter heads (including one of the first stereophonic cutter heads, incorporating a miniature radar within the head to detect stylus motion, all powered by vacuum tube electronics) and recording electronics, such as the legendary Fairchild 670 compressor, designed by Rein Narma, along with the 660 (the mono version of the 670), in the 1950s.

Returning to photography, the lenses produced by the aforementioned companies were of outstanding quality, never failing to impress, even nowadays. By the end of World War II, these companies had considerable expertise in manufacturing very solid, high-quality products, that were already established in their markets. However, the end of WWII saw competition trying to establish a foothold right on the home turf of these giants. Not only was this a rather ambitious move, but it has also proven a highly successful one! Nikon, Canon, Pentax, Minolta, Mamiya, Bronica, and other manufacturers of photographic equipment quickly established themselves in the Western world. What they had in common was that they were all from Japan. Some of these companies produced lenses that could directly compete with the very best of the Western manufacturers, such as the Nikkor camera and enlarger lenses, or the Mamiya-Sekor series of lenses. They won over a substantial portion of the consumer market and many professional photographers were using them during the film era, but also after the market went digital, where Japan entirely dominated the market worldwide.

Nikon in particular had a long history. It was established in 1917 as Nippon Kogaku, in what was then the Empire of Japan. However, it was not until after the end of WWII that they became consumer- and export-oriented. Prior to that, their focus was on optics for industrial and military use, for the domestic market in Japan. When Japan started exporting photographic equipment, Nippon Kogaku often manufactured and supplied the lenses for the other Japanese manufacturers, such as Canon. Canon itself started as the Precision Optical Instruments Laboratory in 1933. Pentax originated in 1919 as the Asahi Kogaku Goshi Kaisha. Evidently, it is not that the Japanese manufacturers did not have a long history of invention and innovation. It was simply that they were not export-oriented for several decades.

Many of our readers will remember when Sony, Akai, Pioneer, Kenwood, Luxman, Sansui, Onkyo, Denon, Tascam, Fostex, Nakamichi, and others arrived on the scene, competing with well-established Western manufacturers such as Altec-Lansing, Dynaco, EICO, Fisher, H.H. Scott, Leak, Quad, Telefunken/AEG, Thorens, EMT, Western Electric and others. Japan was a strong player and their products easily won ground in Western markets. Apart from consumer-oriented audio equipment, Japan also pretty much established the “prosumer” market, of products normally encountered in professional audio environments but made smaller, simpler and usually much more attractively priced. Stereophonic and multitrack tape machines from companies such as Tascam and Fostex had quickly found their way into recording studios, broadcasting facilities, and the bedrooms of ambitious musicians and enthusiasts with the means or determination to be able to afford one. Otari took the concept a bit further, introducing a range of widely-respected professional tape machines that were often seen in studios and advertised in the trade publications of the time.

Tascam and Fostex went on to introduce multitrack recorders using cassette tape as the recording medium, a very attractive solution for anyone on a tight budget, which opened up the way to multitrack recording and endless experimentation in home studios and bedrooms. These units often came with a built-in very basic mixing board with microphone and line inputs, as a sort of studio in a box. The quality could not compete with professional recording equipment and wider tape formats, but neither could the price!

 

Originally a Tascam 414 MK II cassette tape 4-track recorder with a built-in mixing board that served as the author's first multi-track recording device, it was soon discovered that the weakest point was the built-in mixing board electronics. J.I. Agnew gutted it out and replaced it with inputs and outputs for connecting an external mixing console of much higher performance and capabilities. Countless recordings on cassette tape and a variety of odd jobs later, the author was finally able to afford professional recording equipment and the rest, as they say, is history.

Technics introduced a range of sturdy direct-drive turntables oriented towards the broadcasting sector, where they were widely appreciated. The Technics SP-10 and the similar models of that range were often seen in broadcasting studios, having effectively replaced the idler-driven Western counterparts. The SL-1200 established itself in the DJ market and could be found in nightclubs all around the world, earning a reputation for its ability to withstand all kinds of abuse.

Above images: The Technics SP-02 was introduced as an aftermarket motor for the Neumann VMS-70 disk mastering lathe, intended to replace the Lyrec SM-8 synchronous AC motor that was originally used to drive the platter of the VMS-70. Unlike the SP-10, it was not a turntable. It was only the motor, designed to bolt directly onto the Neumann lathe bed, in place of the oil coupler (see Issues 157 and 159 for details), which had to be removed. It did not come with a platter. Instead, it was designed to support the massive Neumann vacuum platter. The drive electronics and control system were housed in an industrial-grade 19-inch rack mount enclosure. It was never offered as a standalone turntable or in versions that would be compatible with other disk mastering lathes. Only around 10-11 SP-02 units were ever made.

Technics, Denon and JVC entered the disk mastering market. Technics and Denon both introduced aftermarket direct-drive motors for use with the popular disk mastering lathes of the time. JVC focused on the quadraphonic record market, developing playback technology and cutting electronics based on modified Threshold Stasis 2 amplifiers, while re-branding Ortofon cutter heads as JVC to offer a complete system. Ortofon had developed a cutter head that was specifically intended to cut masters for the CD4 and other quadraphonic record systems, where the two rear channels were recorded in the same groove as the stereo channels, modulating an HF carrier, above the audible range.

The quadraphonic record formats saw relatively limited success, and so did the efforts of Technics and Denon with their disk-mastering lathe motors. The disk recording and mastering market was quite diverse prior to WWII, but quickly shrank to just four manufacturers as soon as tape recording became established in the 1950s. It became a small niche market which was extremely difficult to penetrate. Neumann was based in Germany and offered turnkey solutions. Scully was based in Connecticut in the US, and only manufactured lathes without any audio electronics. Westrex, the Western Electric Export Company, also in the US, manufactured cutter heads and cutting amplifiers, and Ortofon in Denmark also manufactured cutter heads and cutting amplifiers. While there were countless manufacturers of monophonic cutter heads prior to World War ll, only a select few attempted to develop a stereophonic cutter head. By the 1970s, only Ortofon, Fairchild, Westrex, Cook, HAECO, and Neumann had endeavored to make a stereophonic cutter head. Of these, only Ortofon, Westrex and Neumann moved on to production in significant numbers (it must be noted that in this sector, anything over 10 units constitutes significant a significant volume of production).

So, is the story of Japan’s involvement in disk recording that brief? Not at all! As we shall see in the next episode, Japan quite successfully established the idea of a consumer or prosumer disk recording lathe, at a time when the rest of the world had long abandoned the notion!

So, is the story of Japan’s involvement in disk recording that brief? Not at all! As we shall see in the next episode, Japan quite successfully established the idea of a consumer or prosumer disk recording lathe, at a time when the rest of the world had long abandoned the notion!
