1.2M is 5.25" and 720k is 3.5"
Obviously, you don't work with much Japanese gear and have little
experience with pre-IBM PCs. I've got a few Teac FD-55Fs for example,
which are 96 tpi 300 RPM 5.25" drives.
It was the NEC convention to use the same format from 8" to 3.5" media.
Even the 5.25" drives were high-density only. So the 3.5" version of
the format spins at 360 RPM, just like 8" and 5.25" HD.
