Magnetic Reference Laboratory

Magnetic Reference Laboratory (MRL) is an American company founded in 1972. They make and sell Calibration Tapes[1] for analog audio magnetic tape reproducers in the Open Reel format.

Origins

In 1972 John G. McKnight was laid off from Ampex, as was Tony Bardakos, who was making the calibration tapes for Ampex at the time. Along with Ed Seaman (also an ex-Ampex employee), McKnight and Bardakos decided to start their own calibration tape business, and thus Magnetic Reference Lab (MRL) was born in 1972.[2]

Products

MRL makes a wide variety of calibration tapes (a tape that "contains test signals used to calibrate a tape reproducer so that it will conform to the accepted standards"[1]) that are sold world-wide. Examples of available test signals include:
