Hi Pete,
I'm no guru but somewhere I read that the track width
used is mostly controlled by the head size. So, as they
found ways to make smaller heads then they could get more
tracks on the same size medium. But, what you say also sounds
correct that there is a difference in the intensity of magnetic
alignment induced into the recording medium.
