Unfortunately, just because you can get a 40-track drive to half-step
between tracks, you can't use all 80 tracks.  This is because the 
disk drive head will read/write tracks that are too wide.

Yes, some software uses the intermediate half-tracks for copy
protection, but they then never use either of the normal tracks on
either side of the half track.  (All used portions of tracks are always
atleast a full track apart).

The color computer is not the only machine with software driven
stepping motors that allow half-tracking, the apple ][ does too.
