National Audio Company Factory Only U.S. Company to Make Internal Tapes for Audio Cassettes


SPRINGFIELD, Mo. — A factory in downtown Springfield will soon be the only place in the country, maybe even the world that makes the internal tape that goes inside audio cassettes.

The National Audio Company’s factory makes more than 10 million cassettes per year.

The Springfield News-Leader got to take a tour of the facility.

There’s been a worldwide shortage of tapes mostly because manufacturers simply stopped making the dated technology.

But the president and co-owner Steve Stepp said after getting the right equipment, the process is a lot of trial and error.

“Nobody has made cassette tape in this county since about 1983 or 1984,” Stepp said. “So, the art is not lost, but the art has to be relearned. Learning the chemical mix, learning the mechanical part of it, and learning the thermodynamics of heating and cooling it properly.”

National Audio will begin production of the tape inside cassettes this month.

The company has re-engineered a machine that use to make credit card strips to do the job.

It will crank out 20,000 feet of tape per minute.
