PC 720K, Mac 400k/800k, PC 1.4M, Mac 1.4M disks all

And Amiga 880K (just at 11 sectors of 512 bytes per cylinder due to
the short sector-to-sector gap as a consequence of treating the entire
track (vs a single sector) as a writable entity) as well as the 150RPM
1760K disks (Amiga high density).
All the same track density - just different amounts of data per track.
