Absolute Method for Aligning Magnetic Recording Track Using Electrical Technique
Since the early days of magnetic recording, the precise alignment of the magnetically recorded wavefronts perpendicular to the direction of tape travel has presented a difficult problem. The best existing method involves making the sound track visible and checking azimuth with a microscope. It will be shown that a phase cancelling technique presently used for aligning magnetic gaps in multitrack recording can be extended to permit a precise adjustment of recorded azimuth.
