All 3.5 floppy drive heads are the same size, as they're all
80-track*. Head size only ever causes an issue when switching between
(5.25") 40 and 80-track disks and drives, as the 40-track head is
twice the size of the 80-track one.


* Something is niggling in the back of my mind that there may have
been some 3.5" 40-track drives in existence, but I'm not quite sure. I
know some early Atari STs used single-sided 80-track ones.
