The media MUST be able to pack bits closer. (Higher density)
Even at higher spindle speeds you have to flip the dipoles.
You use higher current in the record head to get a bigger signal
out of the read head.
You do that be using a polished and *harder* (magnetically) medium.
The old soft style head can not successfully record and the read
head gain is too low the successfully read.

Generally, I've found that the High Density
disks are all but unusable in
these older computers/disk drives. . .found that out the hard way when I
bought a C128 with a 1751 disk drive, and tried to format some HD disks .
..for a while I thought the disk drive was broken!
I agree here. I've had exactly the same experience with 3.5" disks and
went through the same hell trying to determine exactly what was wrong.
But it still defies sense. Surely, if the disk has a higher density, it
should be able to be formatted on a lower density drive. What's so
different?
