These papers discuss both theoretical and practical matters related to analog tape recorders,
and supplement the information given in the manufacturer manuals.
The Standards (for instance IEC Standard 60 094, Part 1), and the tape recorder manuals, both say to set up your
tape reproducer gain and equalization from a "Calibration Tape" such as MRL makes. But you may have wondered how MRL measures the
response and fluxivity in the first place. Well, we do it from first principles that are explained in the technical paper "
Flux and
Flux-Frequency Measurements and Standardization in Magnetic Recording". Another paper, "
Tape Flux Measurement Revisited", explains both an
ac and a dc flux measurement in detail, with examples.
MRL President Jay McKnight has published over 70 papers on analog magnetic recording and audio engineering. Topics include
the design of magnetic recording heads; the magnetic erasing, recording, and reproducing processes; signal and noise
considerations; frequency and wavelength response, measurements, standardization, etc.; audio systems and practices; program
level indicators; tape transport design, flutter measurement, etc.; and miscellany. Many of these were published in the Journal of
the Audio Engineering Society. They are listed in the
Bibliography of papers by J. McKnight, and many of the PDF files of the
papers are linked there.
MRL has been a Sustaining Member of the Audio Engineering Society since 1976
