At the risk of over zealously picking nits here, there are at least three
different standards for two track and/or half track widths.
In order of narrow to wide differences there are: 1) Ampex, 2) NAB and 3)
Euro standard widths. If you use a narrower playback head than the recorded
track width, you will experience the "fringing effect" which is a low
frequency boost below 100Hz.
