Anyone know what they're actually doing? Amiga uses standard MFM to get 1760KB on the same density disks, by leaving off the inter-sector gaps and reading and writing a track at a time. If you also leave off all the sector headers you get 1970KB (you nead one gap/sector header to mark the beginning of the data, or you'd be all the way to 2000KB).
