Highland Laboratories Homepage Button		 Standard Tape Manual

The Standard Tape Manual was compiled by Robert K. Morrison, who was the manager of America's leading magnetic test tape manufacturer for ten years. He founded Standard Tape Laboratory, an outstanding producer of audio test tapes. Morrison, an international authority in this field, recognized the need for compilation of material used in the standardization efforts. The Manual is 122 pages, printed on heavy paper ( 8 1/2 x 11 ) and is a limited edition. Charts and monographs, held by a laboratory type binding, may be flattened out for easy computation and reference.

 Standard Tape Library
The seven sections cover:
  • Head Loses - Gap losses, core losses, spacing losses
  • Flux Levels - Normal, elevated and relative difference chart
  • Azimuth - Determination, results of misalignment to phase error in various track configurations, level loses due to azimuth disagreements, five charts.
  • Reproduce Amplifier Response - Definition of induction loop responses and amplifier characteristics
  • Amplifier Curves - Induction loop response curves, ideal response charts
  • Wavelength charts
  • Practical Techniques of Measurement
 The section on measurements includes:
  • How to make induction loop measurements
  • How to measure constant current through the record head
  • How to measure track widths
  • Losses to recorded signals
  • How to measure distortion
  • How to check for magnetized components and other electrical fields causing unwanted erasure and noise
  • How to check for head resonance
  • How to check for static noise caused by ungrounded heads and how to remedy
  • Wear patterns

The Manual is a valuable data book for the audio tape recordist, engineer or designer. It is not a text book, but rather a data reference source for sophisticated users of magnetic recording equipment. It is a practical tool for those who are familiar with the fundamentals of magnetic recording and simply require a quick source of reference data to "plug in" to their routine endeavors, and is a definite must for anyone concerned with professional quality audio recording and magnetic tape.
