Since there is only so much surface and the disks rotate at the same rate
for 360k and 1.2Mb the tracks MUST be narrower. Also, you will see when
you format them, the 360k formats 40 tracks and the 1.2M formats 80 tracks.
This still only doubles the capacity so the linear bit density must also
increase to get you up to 1.2Mb. The diskette quality must be better also,
because a small defect that is ignored at 360k density can wipe out the
signal at 1.2M density.
As for the 720k and 1.4M densities, they also must have different track
widths by the above argument. Not from any particular knowledge I have
on these tho. Only used 1 box of 720ks in my life. :<G>
