Hutchinson Technology

Hutchinson's primary products are suspension assemblies that hold magnetic read-write heads at microscopic distances above the disks in rigid disk drives.

Hutchinson Technology was founded in 1965 by Jon Geiss and Jeffrey Greene, initially to produce gyroscope components for missiles.

It subsequently supplied printed circuit boards to Minnesota's two largest computer companies, Univac and Control Data.

With contracts from Control Data and IBM in the 1970s, it developed specialized mechanisms that precisely position the read-write heads for magnetic disk drives.
