Some of the four-track in-line heads cheated down a little from the
standard 43 mil track width, but I think it was down to 38 mils to allow
for better crosstalk. This is not well documented...but then again we
have a variation of at least 75-82 mils in "NAB" two track heads. At
this point, if one is dealing with more than three tracks on 1/4-inch
tapes there are usually larger issues than this.

Quality tape transfers -- even from hard-to-play tapes.
