There was a hacked driver you could get that would tighten up the tolerances of the stepper motor and get from 1.5 to 1.9 MB of data onto a single floppy, but sliding the tracks closer together.

There was I believe at some point a game that shipped 1.5MB disks as a copy protection mechanism. But if you had this tool you could copy them anyway.

Are you referring to 2M/2MGUI? That didn't change the track spacing (which is fixed) but used bigger sector sizes (similar to how HDDs went from 512B to 4K physical sectors):

No they definitely did more tracks, but it seems to be a smaller multiplier than I recalled.

2-5% more tracks, 12.5% more sectors.

The track spacing didn't change, but yes, many if not all floppy drives could step the head slightly past the officially supported number of tracks.
